l not be a problem with concurrent messages　　 from a given device. However it is possible for concurrent messages to occur a) when　　 a device sends another message before a response is received to a previous message　　 and b) multiple devices may send messages simultaneously to a given device so that　　 it receives a number of messages concurrently so that multiple devices each send　　 multiple messages to a targe fuel dispenser t device.　　3.4.1 Ambiguity of Block Cut Messages　　February 2006 IFSF - STANDARD FORECOURT PROTOCOL FP2_1.90　　 COMMUNICATION SPECIFICATION　　 Page: 25　　 It is important that there should be no concurrent block cut messages from any one　　 device since the header for a block cut message does not contain a token.　　 MESSAGE HEADER = LNAR LNAO IFSF_MC BL　　 Thus it is not possible to recombine block cut messages correctly if there are　　 concurrent block cut messages from a given device.　　3.4.2 Ambiguity of Response Messages　　 There may be confusion about which particular AnswerAcknowledge response　　 pertains to which original ReadWrite message. Since some Read messages also　　 receive Acknowledge messages there can only be one sequence of tokens not　　 separate sequences for Reads and Writes. Hence the maximum number of outstanding　　 messages from a given device should be 32 or less.　　3.4.3 NACK Reads　　 There is a limit to the number of messages which a target device can buffer. In the　　 case of messages overrunning the target device it could NACK any messages beyond　　 its capacity using MS_ACK = 07 (Device busy).

unnis are not happy. Their leaders, as well as Mr Allawi s supporters, say that the UIA s strong showing in ethnically mixed provinces like Baghdad owes more to gangs of Islamists who stormed into polling stations intimidating opponents, and sometimes demanding to vote several times, than to the real demographic balance. Those challenging the results have organised demonstrations in both the capital and the provinces—one of the first times that Sunni leaders have use fuel dispenser d street protest to influence politics—calling for a re-run of the election and threatening to boycott the parliament if their demands are not dealt with. A re-run is almost certainly out of the picture, as both America and the UN have said the election was free and fair enough. The Independent Electoral Commission of Iraq is reviewing results and, in a sop to the Sunnis, has flown in a team of international experts to monitor the handling of the complaints. The commission says it may annul the results from polling stations where egregious offences took place. That, however, is not likely to alter the outcome. Serious offences almost certainly occurred, but probably not on a scale large enough to shift more than a handful of seats. Most observers feel that the preliminary results more or less reflect the political loyalties of the country. One difficulty stems from the insistence of many Sunnis that their share of Iraq s population is not the 15-20% normally estimated but over half. This attitude makes many Shias inclined to belittle Sunni grievances. If the former ruling minority cannot accept that it will no longer rule a democratic Iraq, they argue, then the only course of action is to ignore them until they do. However, the Sunnis and Mr Allawi also have better-founded grievances. The electoral commission could have done much more to inspire confidence in its ability to punish electoral infractions in both last January s election and October s referendum. The commission conceded that instances of fraud had occurred, but fuel dispenser fuel dispenser
