RecursiveMutexTester deadlock

[bretalfieri]

When running with boost through visual studio, RecursiveMutexTester does not exit. I assume there is a deadlock.

REPRO:

• Generate with:
  cmake -DTURF_WITH_BOOST=TRUE -DTURF_PREFER_BOOST=TRUE -DBoost_USE_STATIC_LIBS=ON -DBOOST_ROOT=D:/boost_1_60_0 -DBOOST_INCLUDEDIR=D:/boost_1_60_0/boost -DBOOST_LIBRARYDIR=D:/boost_1_60_0/lib64-msvc-14.0 -G "Visual Studio 14 2015 Win64" ..
• Build and run SynchroTests.
