Hi Guys,

 Yep, I couldn't remember exactly what the issues were. Thanks for digging
that up, Andrzej. So, yeah, anyways it may make sense to update
nutch-site.xml with the comment below, with "performance problems" replaced
with "intermittent problems with the underlying commons-httpclient library".

 If you guys agree, I'll add the comment to nutch-site...

Cheers,
  Chris
