Err, as a software programmer that has to write software that works on
Linux, BSD and OS X, I disagree. :-)

OS X is not even quite BSD anymore.  It's *better* than FreeBSD at any
rate, at least in the memory map department for sure.

I have this hate for FreeBSD mmap because it sucks so much.  It takes
*ages* to msync a map in FreeBSD because the OS doesn't track what parts
actually changed.  They *say* you're supposed to sync just the parts of
the map that you changed.  Bah!  Add all that tracking just for BSD when
Linux can sync the entire map is micro-time?  Instead in my app BSD just
gets no sync at all until the very end.  Take that BSDers! :-)
