Earl Ou e44cbe724b sim: handle async events in main thread only 
In the current implementation pollqueue is not thread safe. The design
of multi threads handle async events is thus causing issue in parallel
environment. Given the low rate of async events, it should be OK to only
handle them in the main thread to avoid unexpected racing issues.
