[Bug 42377] WSASend() returns invalid number of bytes when both lpOverlapped and lpNumberOfBytesSent

--- Comment #12 from Evgeniy Polyakov  ---
Yup, that sounds like the cause, it is consistent with what we see.

Another hint is that WSASend() sometimes immediately returns completed
operation, i.e. without queuing anything, and probably sometimes in this case
it returns number of bytes written in the previous operation - in this case
there is no GetQueuedCompletionStatus() at least in the error trace, but maybe
was wrecked previously.
