When I try to update minitest in trunk and run my tests I get the 
following error:

% ./miniruby -I./lib  ./tool/runruby.rb --extout=.ext -- -Itest 
test/minitest/test_minitest_unit.rb
Run options: --seed 61066

We've inspected the code and don't see how/why this is happening on our 
side. This can be repro'd against `git clone 
git://github.com/seattlerb/minitest.git` or even `gem unpack minitest`. 
I believe this is related to the other thread bugs we've seen but it is 
harder for us to track down.

This is preventing me from merging to trunk.

I double checked and r37921 runs clean.

Sorry. No. 37921 is the first bad. 37920 runs clean.

"minimal" reproduction:

require 'minitest/metametameta'

class TestMiniTestUnit < MetaMetaMetaTestCase
  parallelize_me!
end

thanks to ko1 for the reduction.
