Abstract
A thread interruption function in a multi-threaded runtime environment places a first thread in an alertable blocked state that is interrupted by another thread upon request. The interrupting thread causes an asynchronous procedure call (APC) to be queued against the blocked thread. A callback procedure associated with the APC is executed in a context of the blocked thread and an indicator is stored in the context of the blocked thread. The indicator is captured by runtime environment exception handing which causes the blocked thread to be activated.
