If you're on a POSIX system, you could use the usual fork/exec/wait:
import os
for lstArgs in pileOflstArgs:
pid = os.fork()
if not pid:
os.execv( app, lstArgs )
for i in range(len(pileOflstArgs)):
pid, status = os.wait()
Of couse, os.wait() will block until a child exits. Look at the docs
for the status code it returns, though, as it's not just the return
value of the process.
