This is not true in general, and I don't know of any bugs in this area
that cause connections to close when the window closes.  There was a bug
in 4.2 that could cause connections to close if the window was retracted
after data had been sent into it; I believe that this is fixed in 4.3BSD
as well, although I didn't take the time to set up a situation in which
to test that.
