# On 1.8.7, it's in the stdlib.
# We don't want to load the stdlib, b/c this is a test tool, and can affect the test environment,
# causing tests to pass where they should fail.
#
# So we're transcribing/modifying it from https://github.com/ruby/ruby/blob/v1_8_7_374/lib/thread.rb#L56
# Some methods we don't need are deleted.
# Anything I don't understand (there's quite a bit, actually) is left in.
# Some formating changes are made to appease the robot overlord:
