Log: Fix sporadic crash in the RequestInterruptTestWithNativeAccessor.
The test was broken. V8 currently does not correctly lookup
NativeDataProperty accessors attached to the PrototypeTemplate of
FunctionTemplate (Issue 3066). As the result while(obj.shouldContinue) loop
was immediately exiting and the test would terminate while
RequestInterruptTestBase::InterruptThread would be still starting up. As
the result later InterruptThread would try to access members of the test
object which was destroyed.
The test was fixed:
- instead of attaching accessor to PrototypeTemplate we attach it to
InstanceTemplate;
- an assertion was added to verify that we completed the test successfully
due to interruptor firing not due to sporadic loop termination due to some
unrelated bug.
