I've prepared a somewhat cleaner patch that solves the problem without
using sleep. It increases the modification time by one second
immediately prior to each commit. I added calls everywhere I think the
problem could potentially occur.
I've had no failures with the patch (without it, they are quite frequent).
Cheers,

Subject: [PATCH] Work around Subversion race in git-svn tests.
Some of the git-svn tests can fail on fast machines due to a race in
Subversion: if a file is modified in the same second it was checked out
(or in for that matter), Subversion will not consider it modified. This
works around the problem by increasing the timestamp by one second
before each commit.
