os.execlp and stdout

[Melissa Wallis]

In a Python script I start a number of C++ processes using os.execlp. Most
of these processes output messages for debugging purposes at this time.  The
problem I am having is that by starting 4 or 5 processes from my Python
script I don't get the cout messages they write.  I have tried redirecting
stdout to a file but I get everything but the output from the C++ processes.
Any suggestions.

Thanks
Melissa
