	Ok here goes,
		Suppose you set a process running in the background,
(any sort of process script, compiled programme etc ) does any one know
how to do the following
	
	1:Halt the programme and restart it at a later time from where
it left off.( Effectivly swap it out then swap it back in on some
command.)

	2:Alter its priority, either up or down.

The first could be achived by trapping a signal in the programme and
going to sleep until another signal was trapped BUT can it be done with
out making any changes to the code?

		Thanks in advance
