This is excellent.  Thanks!

However, there is a major practical problem: this currently uses a huge
amount of server-side CPU.  On a Linux kernel repo, for example, it
takes 20 seconds for cmd=branchview to respond, and hg is running at
100% CPU the entire time.  This is on a very fast machine, too.  It
doesn't seem to matter how many revs you want to view; the amount of
server CPU consumed stays constant.

I couldn't generate a profile (Python's hotshot module raised an
exception with threading turned off), so I can't directly tell you
what's wrong.
