Fix executor/TEST106 This change adds synchronization between the sqlci running the subject query and the sqlci which cancels that query for the escalation test case and the update statistics test case. It also logs and tests the ordering of events recorded in T106_interleaved_log, to make it easier to debug the test. Finally, it increases the timeout interval in the synchronization helper script to 10 minutes.
Fix child/parent query IDs for update stats Failure to setup child/parent query IDs for update stats and other non-embedded compiler scenarios caused problems in cancel including frequest but intermittent failure of executor/TEST106. This change fixes the problem.
