Description
One of compiler/rtm/locking/TestRTMLockingThreshold testcases verifies that method will be recompiled on low abort ratio w/ LockingThreshold=0.
Test artificially abort every second transaction, so with LockingThreshold=0, first abort will happened on second transaction. Test verifies that there is exactly two transaction's and one abort.
However, abortion may happen during first transaction due to h/w interrupt. In this case method will be recompiled after first abort as it should, but test will fail because there will be only one transaction.
This issue is very intermittent and reproduces ~ once per 1000 runs.
