I am horribly depressed to report another Darcs failure.  Both Darcs 1.0.9 and Darcs 2.0 go into an infinite loop when pulling 18 patches from the GHC head repo.

My own repo is pristine: I don't have any local changes.  Ahem... except I removed utils/hsc2hs as per a message from Ian.  But that should not cause a loop should it?

Below is the dump from my screen.  I killed the process after it had consumed 100% of the CPU for five minutes.

What really worries me is that this stuff happens on a regular basis.  I just don't trust Darcs any more.

PS: I did a 'darcs revert -a' to put back the missing utils/hsc2hs directory.  Then 'darcs2 pull -av' went through just fine.  So this time I'm not stuck.  But going into an infinite loop because of a local change just isn't confidence building.
