Given those alternatives, I'd much rather add a tryLockEntry() :) Let
me discuss with some people here internally and see whether we can add
this for the 3.2 release train.
I'll leave the interrupt question to Chris (who is out today) since he
just rewrote the client lock manager. In this case, I think you're
performing a blocking lock operation so I don't believe it should/
would respond to interrupt.
BTW, you might want to try out some of your perf tests with the
current trunk - server guys have made some insane improvements in the
last few weeks in prep for 3.2 plus the new lock mgr is a big
improvement, particularly on read locks and lock memory footprint.

My only concern with that is that LockableMap touches a lot of

tim-hibernate-cache, etc:
I see your concerns ...
Maybe it would be better to add it just to ConcurrentDistributedMap
directly
and not LockableMap for the moment?
I was thinking at LockableMap in order to be consistent with already
existing interfaces: adding such a method directly on
ConcurrentDistributedMap would absolutely work for me, but I don't
want to mess your code, so feel free to review the issue with your
transparency team if needed and keep me posted.
As an alternative solution, I was thinking to write a
ContentionManager to simply kill threads contending/waiting-for locks
for too much time, so I have another question: is it possible to
interrupt a thread waiting on ManagerUtil.beginLock(...)?
