I gave this a spin (with a r1536831 checkout). Some results of `make check

Ubuntu 12.04 on a VM (disk I/O is slow):
subversion/tests on RAM disk: 8:22.25 (m:ss)
subversion/tests/cmdline/svn-test-work on RAM disk: 12:05.16 (m:ss)
subversion/tests/cmdline/svn-test-work on RAM disk (without r1536700): 12:03.78

OS X 10.7.5 (SSD, disk I/O is fast):
subversion/tests on RAM disk: 9:47.735(m:ss)
subversion/tests/cmdline/svn-test-work on RAM disk: 9:52.231 (m:ss)
subversion/tests/cmdline/svn-test-work on RAM disk (without r1536700): 10:6.924

So it appears to nominally help. But mounting all of subversion/tests still is
much better for me on my VM with slow I/O. As in the past mounting all of
subversion/tests on OS X isn't worth the added hassle that it entails.

The extra time on the VM run is probably just a fluke. I was only running this
to see if I could ditch the subversion/tests mount on my VM.
