Running the "python build/build.py run" command starts up the java server, but it seems to exit as soon as return is pressed in the terminal window.  Additionally, the python process seems to start and replace itself with the java process which causes setting up a launchd (cron-like) job to keep it running futile, since launchd sees the python process exit and tries to restart it.

(This is the validator.nu java servlet)

I'm starting to play around with replacing the os.execvp commands in build.py runValidator() with os.spawnvp instead, hopefully keeping the python process around so that it can monitor it's child and prevent launchd from thinking it's exited.

Can anyone think of a reason this would be a bad thing to do?
