[nflug] osx

[Darin Perusich]

OS X uses the Mach 3.0 macrokernel and FreeBSD services, at aleast 
according to http://www.apple.com/macosx/features/unix/. though for 
those who are interested microsofts SFU (services for unix) IS OpenBSD. 
if you run strings against the binaries they are riddled with ident tags.

the bsd license doesn't require the publishing of the source code only 
the copyright notices. i read an interview with theo de raadt, the 
OpenBSD project lead about this and he said because the internals of the 
systems are different you can't just implement from looking at the other 
systems source code. though i think this was related to SMP in the kernel.
