hi there,

I dumped the contents in segment/fetchlist and
segment/fetcher;

My curious question is that: why MD5 signature of the
page content doesn‘t save in fetchlist? 

In my mind, I think it will save CPU time if we see a
page unchanged --- coz we can skip the parsing
process; From my view, if we have MD5 in fetchlist, we
can do it directly in memory. If we have MD5 in
fetcher, we need to search it in local file in order
to do compare with the new fetched page content MD5.

Did I miss some important points or my dumping is
wrong?

thanks,

Michael Ji
