Hmm.... I wouldn't think so. You should still be able to spawn object
instances, but I'd say it scopes the lock to the whole class, so that
everything in that container is locked any time anything in the class
in accessed. It's a cheap way to make all shared resources queue up
nicely, if you just want a quick and dirty script instead of something
well streamlined. Kind of like locking at the DB or table level instead
of just the row, but there are times when that's what you need.
