The logic there is ok i guess, as i already noted later in the thread.
As the handles also leak using posix threads under cygwin,  i guess the 
posix thread implementation does something similiar. The  problem is that 
when the mutex is done with pthread_mutex_destroy() should be called. 
gcc's gthread interface used in libfortran however does not however have 
this functionality as far as i can tell from the sources.

Anyway, Jerry idea of reusing the internal unit structure would 
effectively solve this problem, being also a good thing otherwise IMO.
