Fixes lock brokenness
Comment 1 Lon Hohberger 2005-10-19 23:08:28 UTC 
Description of problem:

This causes rgmanager to break under lock contention and raise "Resource
temporarily unavailable" messages if multiple instances boot at near or exactly
the same time.

Rgmanager calls clu_lock() which is supposed to wait until a successful lock
grant has been issued, or unrecoverable error has occurred.  Due to a bug in
magma_gulm.so, it returns immediately - with -11, errno=0.  It should return
EAGAIN so the clu_lock() function will correctly retry.
