3754	Multithread problem in Named Mutexes	Alex Sobral de Freitas <alexsobral@…>	Ion Gaztañaga	"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 ""/ boost_1_40_0/boost/interprocess/detail/managed_open_or_create_impl.hpp"" 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."	Bugs	closed	Boost 1.42.0	interprocess	Boost 1.40.0	Not Applicable	invalid
