"hg up" hangs on a simple test case

[Sergey Dolgov]

Hi,

I'm playing with mercurial and observing the following:

$ hg clone http://selenic.com/repo/hg             # could be any repo
$ cd hg
$ hg up 1000
$ hg up

The last command then never returns, eating 100% CPU time. However,

$ hg up -C

succededs and does what is expected.

I've tried both versions 0.9.3 and 70d1491d3db2 (latest at
http://selenic.com/repo/hg ATM).

Is this a known problem, or maybe a feature?

(I'm almost sure it is known, but I can't find an explanation)

Thanks!
