LockSet: handle empty case

A LockSet is mostly useful when it has some locks in it. On the other hand
there are cases in which it must function even when empty. For example if a
cluster has no instances in it there's no reason why locking all of them
shouldn't work anyway. This patch adds test code for that situation and...

LockSet: improve remove() api

LockSet: invert try/for nesting in acquire()

This patch changes nothing to the functionality of a LockSet. Rather than
