I'm not sure about all cases, but maybe in general use curl mostly closes
connection itself like in those tests that work anyway.

Further investigating shows that problem is with cygwin poll function it
doesn't signal that there is data
after connection is closed from other side. If undefine HAVE_POLL_FINE tests
also work.

I'll try to ask Cygwin developers, about such behaviour of poll.
