mmap works -- you just can't do MAP_PRIVATE. Everything has to be MAP_SHARED. There is no fork (though vfork works). brk doesn't work, and things like iopl, ioperm are pointless. etc...
Oh, and when you do malloc something (malloc is mmap based) you really want to remember to free it, since the system can't clean up after you,
