Comment 8 for bug 246891

Note that this bug increases the severity of bug #97715 ("bzr log DIR should show changes under DIR"). Ordinarily 'bzr log -v' would be a good workaround for that, but with 'bzr log -v' essentially unuseable on large / deep-history projects [1], there is no workaround for bug #97715.

[1] About 36 hours (by extrapolation -- it hasn't finished yet) for the 94342-revision emacs-merges-ce-master repository, branched (in 1.9 format) from bzr://bzr.notengoamigos.org/emacs-merges-ce/master/, on a machine with dual core 2.2Ghz AMD Opterons w/ 1024 KB cache each, 4GB ram, 2GB swap, reasonably fast SCSI disks, and not a huge amount of other load.
