During my investigations on recursive mutexes (yeah, FreeBSD) I've found
out that Solaris is rumoured not to support recursive mutexes at all.

Another one bites the dust. OS X seems to be in the same position.

FreeBSD supports recursive mutexes, we just need some code.
For Solaris and OS X, we need a emulation layer.

Looking forward to patches for Solaris on the bug tracker!
Need SUN sponsoring Astricon :-)
