I have a patch available as revision 1516 in the branch at:

           http://delta.univ-orleans.fr/~duchier/bzr/bzr.call_at_end


I can confirm that this was _the_ major bottleneck for "bzr status".
Previously, when running "bzr status" on my linux tree after I had touched all
the files, I had to interrupt the process after 84mn.  With this patch, it
completes in 4mn 51s.

The patch passes the test suite.

The idea of the patch is to extend transactions to allow registering callbacks
to be executed at the end of the transaction.

Cheers,
