The CHECKOUT/PUT/MERGE/DELETE are simply refering to entires in the the
access_log that apache generates throughout a commit. They were just
reference points.

It wasn't a checkout. It was a commit.

One way may be to autogenerate 5000 files and put them in a svn repository.
Append a few lines of code to each file and then commit the files to the
repository through tsvn and the svn commandline. The repo that I was using
had 40000 revisions, so that may cause some issues, but it shouldn't.
