I knew about that. In fact that is the least of my worries as it turns
out.

Well, other gotchas include the fact that memory access exceptions are
delivered via mach ports, signals are delivered on the main/first thread
of a process only, and the kernel's reliance of being compile into an ELF

There are probably more gotchas, but I don't remember them off hand.
