On short write, that patch will write out the content repeatedly, instead of
offsetting to only write what still needs to go out.

So, I wasn't absolutely sure we really were seeing short writes, thus my patch
only added EINTR handling. Your patch fixing things for you suggests that what
is happening is: on SIGHUP, write() is returning 0, a short write of nothing.
Thus you don't see the repeated content, because there was nothing to repeat.

Ugh.

I'm writing a better fix now.
