> In TNamedPipeServer, there exists a race condition between the 'serve' thread 
> and another thread that would attempt to interrupt it.
> While the 'serve' thread is waiting for clients to connect, it is blocked on 
> a GetOverlappedResult call.
> To stop the server, another thread calls the interrupt function that submits 
> a CANCELIO operation to the TOverlappedSubmissionThread.
> The ::CancelIo function is called, freeing the 'serve' thread with an 
> unsuccessful OvelappedResult which then throws and terminate the server by 
> deleting the serverTransport_.
> All this can happen while the call to interrupt has not yet returned, and 
> even the event signaling the execution of the CANCELIO request might not have 
> been caught.
> In our code, this result in unpredictable behavior (mostly detected as 
> stalled).
> It is very hard to reproduce in test environment as it consists in a running 
> threads race condition.
