Suspend process for RT AIX 2.2.1

[Robert Lutwak]

	Because of bus conflicts, we need to be able to suspend and resume
processes running in background, a feature not offered by AIX.  We are
currently requiring users to catch SIGUSR1 and sleep for 10 minutes, but
this is terribly awkward and any program that fails to catch it dies.
	Has anyone out there solved this problem?
	Is there a solution available in public domain?

	Please post here or respond by E-mail to

	Thanks.
