I think it makes sense to use __del__ here. If we use a pager, and we have a long output (e.g. the
mercurial repository) and you quit the pager before mercurial finished to write the complete output
to the pager, you will get a "BROKEN PIPE" from the pager.

To don't avoid people all the time, I think it's better to catch the IOException from python in
__del__ (as this is the only place to do that). It really annoyed me to see the Broken Pipe message
all the time and I think people get confused by that more than that "error" helps them.
