I don't know my way around the bug repository so I can't report a bug
number, but it's a well-known complaint that checkouts are *not* atomic.
  If you interrupt a checkout, or the server goes down in the middle of
one, or something else bad happens, then you can be left with a partial
checkout.

I think this can usually be detected and fixed by trying to update
immediately after checking out; that would normally do nothing, but if
the checkout was incomplete, it should pick up the missing files.
Unfortunately, updates have the same non-atomicity, so it's possible
lightning will strike you twice and you'll still have a bad working copy
after the update.
