subprocess 'wait' method causes .py program to hang.

I calling a Windows executable with PROC = subprocess.Popen('...'), and
blocking further python execution until the process terminates with
PROC.wait().  Occasionally, something unusual happens with the
subprocess, and it fails without terminating the process.  When this
happens, my Python program doesn't detect the error condition, and
hangs.

What can I do about this?
