Holy cow, that was slick :-).

It works, but you could also end up with a corrupt copy. The problem is that
during the copy, you're getting whatever the HEAD is for that specific
request. During the time that you're fetching the tree, five commits could
come in, each drastically changing something about the tree. You'll end up
with bits from rev N through N+4.

That said, if you like to play the odds, then this pattern works
wonderfully. Or if you know the repository is idle. etc.

IOW, excellent trick, but there are some serious caveats to be wary of.

IOW^2, let's not use this recommendation on our website, but leave it to the
power hackers :-)   [okay, well maybe a footnote in a faq or something, "I
copied from the WebDAV mount and ended up with non-buildable crap! what
happened?" and let the big brains reverse that into an understanding]

Cheers,
