[PATCH] ruby test race

On a really slow machine [50 MHz 68060], I got the following in the
ruby testsuite:

  2) Failure:
test_commit_editor(SvnRaTest)
    [svn140]/bindings/swig/ruby/test/test_ra.rb:228:in `test_commit_editor'
     [svn140]/bindings/swig/ruby/test/util.rb:57:in `change_gc_status'
     [svn140]/bindings/swig/ruby/test/util.rb:68:in `gc_disable'
     [svn140]/bindings/swig/ruby/test/test_ra.rb:216:in `test_commit_editor']:
<[1, "Fri Sep 15 01:34:39 CEST 2006", "buildd"]> expected but was
<[1, "Fri Sep 15 01:34:40 CEST 2006", "buildd"]>.

This could happen on _any_ machine, just more frequently on slow ones.
The following patch is untested, so feel free to treat it as a mere
clarification of the problem.

[[[
Avoid a race condition in the ruby RA tests, where the system clock
increments in the middle of the test.

* subversion/bindings/swig/ruby/test/test_ra.rb (test_commit_editor):
  Compare commit timestamp to the system times from before _and_ after.
  (test_commit_editor2): Ditto.
]]]
