I wasn't thinking of a flag, I was thinking of a withTimeout(timeout)
method on AdvancedCache. There may be other "flags" that could be
customized with a value as well, but then you'd need to keep them in a
map and it could be more trouble than it's worth.

The complication with withTimeout/tryLock OTOH is that as a user I'd
expect it to limit everything, not just the lock acquisition - so it
would have to override sync.replTimeout as well.
