Killing the process shall cleanup everything (eventually :-)), if not
it is a bug.

Most of the activity/transaction is driven from the client process in mnesia so
it should work well.

But if you have long search times in dets on a remote node, a queued
request will not be
removed from the inbox of the dets process just because you killed the
requester.

But you can't know if the data was commit'ed or not.
