ugh.. i don't think i read this correctly the last
time, a hit counter in the zodb, is still a bad idea.
a download counter utilizing a btree length would be
more effective. a hit counter would be bad, mainly
because of size bloat in an undoable storage, and (i'm
less sure on this one) from triggering a write
transaction on page views which in zeo setting isn't a
good idea. my current understanding is that in zeo1.0,
only 1 transaction is allowed active at anyone time
among all the zeo clients.
