7682	boost 1.52 named_mutex/named_condition pairing broken	damian.coventry@…	Ion Gaztañaga	"The following program works in boost 1.47, however in 1.52 it does not.  To test it, run 2 instances.  The 2nd instance should output the numbers 1, 3, 5, 7, 9.

Under 1.52, the program outputs the number 1, and then does nothing. The fault appears to be with the named_condition and named_mutex classes.

Tested under Windows 7 Pro, SP1, using Visual Studio 2010 v10.0.40219.1 SP1Rel.  The test was done with a statically linked boost date time, with Platform Toolset set to v90, i.e. linked with the library 'libboost_date_time-vc90-mt-sgd-1_47.lib'.
