Comment (by alex):

 I am the developer of anti-virus, respectively, our product should work
 with any conditions that malicious software may do. We found that the
 boost has architectural problem with the fact that he is trying to get the
 system time in posix format when specifying relative time. We found some
 workarounds solutions, but a problem with the condition variable could not
 solve. Example executed on windows 8.1, visual studio 2012, boost_1_55_0.
 Thanks!
