4010,Boost message queue bug,rusty0831 <rusty_lai@…>,Ion Gaztañaga,"  There is a serious bug within the message queue.
  Originally boost message queue intends to create temp files under a randomly generated temp 
  folder, boost uses undocumented Windows APIs to get the bootstamp to generate the folder 
  name, the folder name looks like ""C:\Documents and Settings\All Users\Application Data/boost_interprocess/D0F325BE8579CA01/"".
  Unfortunately that there is a bug of the method to generate the bootstamp, that the bootstamp
  will vary, even without rebooting!! 
    
  This will cause problems that, if a message queue is running for hours, further request from client cannot
  connect to it because of the newly generated bootstamp is different!!
  
  This bug can be replicated by 
  
[Method 1]
   1. Write a test program (A), create a message queue and let it running for hours (e.g. 3hours...)
      When the message queue is created, a folder under ""C:\Documents and Settings\All Users\Application Data\boost_interprocess\D0F325BE8579CA01""
      will be created. Notice the folder name ""D0F325BE8579CA01"".
   2. Write another test program (B) to connect to the message queue created by test program (A).
      You will notice that it's unable to connect to the message queue created by program (A).
      
      You can also find that another folder ""C:\Documents and Settings\All Users\Application Data\boost_interprocess\9053E2F2EBC0CA01"" is created.
      Notice that the folder name ""9053E2F2EBC0CA01"" is different from ""D0F325BE8579CA01"".


[Method 2]
   There is another more simple method to replicate the issue instead of to wait for hours.
   The steps are mostly the same as [Method 1], the difference is before running test program (B), please change the system time.
   
   Afterwards test program (B) is unable to connect to test program (A) anymore.
