A second later might be too much, but for the case where you need to
add a patch in the middle (which I suspect is the most timeconsuming
and tricky part at the moment), you might want to use a temporary
branch checked out where you need to apply the patch, apply the patch
and then rebase the rest of the history onto that new commit. Rebase
is fairly quick (although not a one-second thing for 20k commits), so
you'll get the time down quite a bit, I imagine.
