This patch causes darcs changes and list_authors to hang (maybe they're just
taking very long?)

Jason thought it might be related to my machine when I had accidentally started
(and interrupted) a rm -rf / (errant makefile).  I've checked the disk, indeed
found some errors and corrected them, but I still get this issue.  

I was wondering if somebody else can reproduce this (MacOS X, 10.4, Intel; GHC
6.8.2 binary from the website)

I forgot to add that cherry picking to unpull the patch makes everything just fine.

I can't reproduce it with GHC 6.6. "darcs changes" just runs on the darcs
repository itself, and on a small hashed darcs 2 repository with 5 patches.

The environment:

$ darcs2 --exact-version
darcs compiled on Feb 22 2008, at 14:18:56
unknown

$ darcs2 query repo

Thanks for trying that!

For what it's worth, the hanging I experienced was on the
unstable-hashed version of the darcs repository

I pulled the unstable-hashed repo, and 'changes' and 'query authors' work fine.

This issue is resolved for me, thanks to this recent patch:
