Comment:

 Similar to #3937.

 The real problem is that there is no IO manager on Windows.  It is the
 communication between the client thread and the IO manager that allows IO
 operations to be interrupted on Unix systems, whereas on Windows with
 -threaded all IO is implemented with safe foreign calls.
