> If a read or write operation on pipes reaches the set timeout, the read/write 
> operation is not properly cancelled. However, the overlapped struct gets 
> freed when leaving the method, which essentially leaves the pending read or 
> write operation with an undefined pointer. 
> Easily reproducible with buffered transport over pipes, a combination that 
> does not work at all anyways. The workaround for both problems is to not use 
> buffered transport with pipes (use framed instead), and some sane tinemouts 
> (not too short).
