Otherwise the child will hang forever on exit when trying to dump the profiling data. Which is problematic when trying to profile some programs. There might be more elegant ways to handle it, this is mostly a proof of concept. Also it's not quite fully working, the test passes alone, but but if ran after some other specific tests, it end up in a SIGTRAP, which I'm not sure why: ``` bundle exec rake SEED=26641 TESTOPTS="-v" ... 1) Failure: TestVernier#test_that_forked_children_do_not_hang [test/test_vernier.rb:15]: Expected #<Process::Status: pid 63146 SIGTRAP (signal 5)> to be success?. ```
