Hi Tatsuro,
This Qt issue should be reported to their developers.  Do you have experience 
opening a ticket with them?  If so, please do so and let me know the ticket/bug 
number.  I will participate in discussion there.  I could also open a ticket 
myself if you prefer that I do it.

It seems to me that we should continue to apply your one-line patch that turns 
off O_NONBLOCK at that one Qt location, as a workaround for this Qt problem on 
Cygwin.  When the Qt devs fix the root cause and release a new Qt containing the 
fix, we can then remove our local patch.


Yaakov: Does this all sound reasonable to you?
