> If shutting down encounters an exception (for example, OutOfMemory), it can happen that
the process does not exit. We have observed this after an NPE from DFS (closing the transaction
log), the process stayed alive and the\ prune thread (executor) was not shut down. It was
not clear why the process stayed alive, but it would certainly help to handle exceptions better
in the shutdown sequence.
