In that case I'd try to have it repaired ;-)

OK, if you want to give a try to my test case:

$ [install darcs]
$ darcs get http://alioth.debian.org/~gismo/darcs-pull-bug/parenscript.upstream/
$ darcs get http://alioth.debian.org/~gismo/darcs-pull-bug/parenscript/
$ cd parenscript
$ darcs pull ../parenscript.upstream/
[choose to apply only the first patch]

At that point, darcs takes 100% of the CPU and temperature starts to
rise :-(

FWIW, the same process on a PIII-500 is running for more than 5819
*hours* and it haven't finished nor spotted an error, yet.

This was exactly my idea: I already know that at least another X60
Debian Developer will be at DebConf8, this is another reason I waited.

Thx, bye,
