Most recent code: http://is.gd/hO85C
I added code for Mac OS X which should use its monotonic clock functions. Unfortunately, as I don't own a Mac, it's completed untested, but in theory, what's there should work, and someone with a Mac can fix it later if need be. I also updated my unit testing functions again (based on the feedback in the thread on a potential std.unittests). - Jonathan M Davis P.S. Remember that you need to link in advapi32.lib on Windows.
