Please review a new version of the change [1]  that fixes the problem with the  debugger not stopping in the low memory notification code. The fix moves the send notifications task from
not visible ServiceThread to a new visible NotificationThread. This version of the  change also introduces  a new VM option to opt-out from the new behavior.

Previous email threads:

The proposed CSR [3] is for adding  a new VM option UseNotificationThread  (default true) to opt-out from the new behavior. 

Testing: Mach5 tests tier1, tier2, tier3, and tier7 successfully passed.
