Thanks for the testcase, but... would you mind to change it to take the
boost lib out of the picture, by using just plain pthread functions, if
possible in plain C?

Apparently someone else has already encountered similar problems in cygwin perl (http://www.nntp.perl.org/group/perl.perl5.porters/2011/07/msg174491.html) last year that went unfixed. Now that you have a test case in C++/Boost, you're asking for plain pthread/C?

The easier it is to demonstrate the problem with a minimum of overhead/code, the quicker the fix. And now that it's reported to the Cygwin list, the problem is at least on the right radar.
