Comment (by nh2):

 OK I have now also checked the situation on Windows:

 Windows `select()` does not set the `timeout` parameter to the remaining
 time.

 So currently `fdReady()` on Windows is as wrong as it is for the BSDs, and
 may wait forever even if given a max timeout.

 Source: https://msdn.microsoft.com/en-
 us/library/windows/desktop/ms740141(v=vs.85).aspx

 {{{
   _In_    const struct timeval *timeout
 }}}

 I'll try to fix it.
