Long lived OpenPBS bug fixed!

All versions of OpenPBS have this problem: the
scheduler uses blocking sockets to contact the nodes,
and if a node is dead, the scheduler hangs for several
minutes, and all user commands will hang (no so
good!).

Scalable PBS finally fixed this problem:

"... In local testing, we are able to issue a 'kill
-STOP' on one node or even all nodes and the
pbs_server daemon continues to be highly responsive to
user commands, scheduler queries, and job
submissions."

*Also*, don't miss the Supercluster Newsletter, which
talked about the next generation Maui scheduler called
"Moab":
