When I do C-x v d ~ RET (C-x v d runs the command vc-dir), I get the
buffer and the message "running hg status -mardui -C . in background"
and the *vc-dir* buffer never actually becomes usable.

This behavior started relatively recently (within the last couple of
weeks).

My home directory is under hg and many subtrees are ignored:

--8<---------------cut here---------------start------------->8---
$ time hg status -mardui -C . | cut -f1 -d' ' | sort | uniq -c | sort -n'
   1 A
   5 M
  19 ?
185661 I

real	0m11.587s
user	0m10.745s
sys	0m1.103s
--8<---------------cut here---------------end--------------->8---

as you see, the hg command completes fast but emacs, apparently, chokes
on the 180k ignored files.
