You want to "sublaunch."  Get your hands on a copy of TechNote 126 (revised
8/1/88) for details.

Note that under UniFinder, sublaunch does what you want.  Under Multifinder,
you continue to run and MUST call WaitNextEvent several times (until you get
sent to the background.  Note also that, under multifinder, you aren't
guaranteed that the child is finished when you get returned to the foreground,
AND that launch RETURNS.

DO NOT USE CHAIN.  Although it is documented nowhere, I have it verbally from
Mac DTS that you should no longer use it.
