The debug output in cygserver is activated by giving the option `-d'
$ /path/to/cygserver -d

No, the mtx_unlock is correct. If you're looking for bugs, they are very
likely in the bsd_* files in cygserver. Even though the sysv_* files taken
from FreeBSD are not proved to be 100% correct, there's a high probability
that I produced the bug in some of the bsd emulation functions. msleep is
a good candidate, FWIW.
Any active debugging or tracking down the bug is highly appreciated,
probably not only by me.
