I think that there's no problem on Linux. Although the lock manager is
often described as if it were a separate process, it's actually part of
the engine code. If your JVM's run from different process groups, you
may get blockages if a process variously called gds_lock or gds_relay
isn't running to relay signals. But the lock code is always there.
