There are some important bugfixes here, but nothing earth-shattering.
In particular, the Lame Delegation detection is massively sped up, meaning
that a lame server can be given up on in a few seconds, rather than taking
75 seconds. This will be a big win for large mailing list machines,
eg: freefall.
Note: this is a remote cvs import... Backups have been made.. :-)
