I doubt it would be fast at all if it even happens.  Unlike Linux, 
svr4, and ibcs2, OS X is not just a POSIXish UNIX kernel.  It also 
includes mach so there would have to be a lot of emulation to support 
that.  OS X also tends to define its interface not at the kernel 
syscall level but at the library API level (from what I have heard), 
which means that it might require having custom versions of the base 
system frameworks ala Wine which would be an enormous amount of work.
