From empirical evidence, the needed number of locks is not dependent
on the size of the commit but on the number of revisions. It's easy to

svnadmin create test
# set the lock values in DB_CONFIG to 20
svnadmin recover test

svn co .../test
cd test
touch foo
svn add foo
perl -le 'while (){ open F, ">foo"; print F ++$i; system qq{svn ci -m "ci $i"}; sleep 1; }'

This fails for me after 87 checkins. Subversion 0.20, Berkeley 4.0.14.
