Some news about SHA1 that is, perhaps, relevant to past
debates among arch hackers.

Not that revc is going anywhere but I'd like to note
for the record that while the current code base happens
to be vulnerable to SHA1 punning, it is *also* *explicitly*
and *carefully* designed so that that is just a ramp-up
condition -- it ultimately does not rely on the security
of any hash function, whatsoever. The design uses SHA1 just as
a redundant check of data integrity and as a source of
significant performance optimizations.
