I forgot to mention that the problem case is exceptional: the problem I have is only in the case of an Intel version of the app trying to launch a PPC-only child the first time after reboot: -launch returns immediately, and isRunning returns YES, but there is like a 3 second delay between the time Rosetta begins to run and my binary is actually launched - it appears that isRunning returns YES as soon as Rosetta is started - not when my PPC child is actually started.
In the Intel-launching-Intel or PPC-launching-PPC case, there is never any problem whatsoever. Maybe I need to add some code to complete *after* Rosetta has *finished* launching.

I'm pretty sure that -launch is synchronous. When it returns, the
subprocess is already running. Are you seeing behavior to the
contrary?
