Jira_subtask_outward CORE3331
Relate to CORE4004

Consider following example :

tx1: update table t ... where id = 1
tx2: update table t ... where id = 1

If tx2's is in WAIT mode, it will wait for end of tx1 forever and this wait can't be breaked nor using DELETE FROM MON$xxx, nor using fb_cancel_operation.

The improvement is to make lock manager able to break such endless waitings.
