I believe so too. And nowadays there's "git gc --auto", which was
made for occasions such as this, so it should be a breeze to
implement. The overhead might be low enough that it can be called
after _every_ imported revision.

Careful. I made the same mistake and it had to be corrected with
e0cd252eb0ba6453acd64762625b004aa4cc162b.

"gc --auto" after every 1000 or so feels like a good default and I
would agree that would be a real fix to a real usability bug.

I think 1000 might be too high; considering that (at least in my
experience) it takes on the order of 250-500 ms to import a commit,
the gc --auto overhead of maybe 10 ms isn't so bad.

A good compromise might be to run gc --auto after every 10-100
commits, _and_ when the import is done.

However, if gc --auto always takes a lot of time without accomplishing
anything in the presence of too many unreachable loose objects it
might not be a good idea to run it at all, since the use of git-svn
involves frequent rebasing.

I don't know much about how this works, so if git gc --auto might have  
a problem, it seems the simplest fix for now would be to default git- 
svn to having --repack=1000 on.

Patches?

Just hot air and noise for now from my end. Sorry.

Same. I don't know Perl. Sorry.
