Use manual reset events for OVERLAPPED I/O on Windows: I/O operations reset
provided event to non-signaled state automatically [1]. Using automatic reset
events is not recommended:
[[[
Functions such as ReadFile and WriteFile set this handle to the nonsignaled
state before they begin an I/O operation. When the operation has completed,
the handle is set to the signaled state.
Functions such as GetOverlappedResult and the synchronization wait functions
reset auto-reset events to the nonsignaled state. Therefore, you should use a
manual reset event; if you use an auto-reset event, your application can stop
responding if you wait for the operation to complete and then call
GetOverlappedResult with the bWait parameter set to TRUE.
