I think its good to address user issues rapidly; but we should at least
attempt to do the correct long term fix before adding workarounds;
workarounds only fix the issue for some users and are really 'unbreakme'
options.

I think there are two things here.
1) Showing many revisions on huge merges will be very clumsy.
2) Its slower than it should be (duh).

For 1, I think we should file a bug for ui improvements.
For 2, please get a --lsprof-file trace and we can probably identify the
issue very rapidly.
