> COUCHDB-1050 shows how an error in a db process can cause unexpected 'EXIT' messages to reach couch_server. These messages cause couch_server to restart, forcing all open databases to close, which has nasty effects like killing replications and index generation in unrelated databases. I suggest we use the couch_dbs_by_pid table to swallow the error, cleanup the ETS tables, log a message and continue. If a match isn't found in the table then the current unexpected message crash should be preserved.
