Code review comment for lp:~vila/bzr/306264-pycurl-recv-error

I was finally able to reproduce the (reported long ago) problem with newer pycurl.

The priority was low because that occured only in torture tests. Yet, it was causing failures on karmic recently.

Hopefully we'll have a clean selftest run now, which makes me quite warmer inside
with 2.0 across the corner :-)
