Some people, particularly our friends from EDG, EGEE, and LCG, run the 
gatekeeper as a daemon, instead of running it from xinetd. 

It would be nice if the gatekeeper made its port reusable, so when the 
gatekeeper is stopped and restarted, you don't have to wait a long time to 
restart the gatekeeper. 

Here is a small patch from David Smith of LCG to provide exactly this 
functionality. It's a short patch, and it is well-tested. We hope it can make 
it into an upcoming Globus release. 

Thanks,
Alain Roy, VDT
