New Revision: 2070

Modified:
   trunk/src/python/opensrf.py.in
Log:
Enhanced do_start() implementation in Python management script

Unclean shutdowns and fork() misery can create PID files that have
no actual process behind them. Instead of just trusting the PID file, check
for the running PID; if the process is not running, then remove the PID file
and actually start the service.
