#3754: Multithread problem in Named Mutexes
 Reporter: Alex Sobral de Freitas <alexsobral@…> | Owner: igaztanaga
     Type: Bugs | Status: new
Milestone: Boost 1.42.0 | Component: interprocess
  Version: Boost 1.40.0 | Severity: Showstopper
 Keywords: |
 I was developing a test for named_mutex and the program began to close
 unexpectedly. The situation occurred with multiple threads simultaneously
 trying to create named_mutex objects.
 Investigating the problem more deeply I have identified that the builder
 tries to create the named_mutex control file ''(in file "/
 line 264)'' and if the control file already exists an exception occurs,
 which ultimately call the operating system ''(FormatMessageA the file "/
 boost_1_40_0/boost/interprocess/detail/win32_api.hpp" line 471)'' and the
 program quits after calling this function.
 This problem only occurs with multiple threads creating named_mutexes
 simultaneously, and I believe it is because this function OS is not multi-
 threaded safe.
