[BProc] clone support

[Nicholas H. <he...@se...>]

Hey Erik~
	I am again faced with pesky Java users who are wanting to use bpsh to
farm out their tasks. I am running low on ammunition to kill them, so I
figured I would take a stab at getting the 'clone' system call working
in bproc. First -- is this going to be possible ? Second - can you give
me a rough overview of what needs to be done ?

Thanks!
Nic
