> Currently the phoenix scripts in python start the java process via
> subprocess.call() or subprocess.popen() even when the java process has to run
> in the foreground, and there is no cleanup required.
> I propose that in these cases, we start java via os.exec*(). This has the
> following advantages:
> * There is no python process idling waiting for the java process to end,
> reducing process count and memory consumption
> * Signal handling is simplified (signals sent to the starting script are
> received by the java process started)
> * Return code handling is simplified (no need to check for and return error
> codes from java in the startup script)
