If the call to AsyncLoadFile() requested allocation of a buffer, this function frees the buffer. If the call to AsyncLoadFile() specified an ioDonePort, you will not receive notification at that port after calling AbortAsyncLoadFile().
Do not call FinishAsyncLoadFile() after calling AbortAsyncLoadFile(); it performs the actions internally.
