-Fibers 1.0.0 has a bug in run-fibers in which peer schedulers aren't destroyed -
-so if you had 4 cores, 1 would be destroyed when run-fibers returned, but the
-other 3 would stay around.  Each scheduler uses 3 file descriptors, so for
-machines with many cores, this resource leak adds up quickly - quickly enough
-that the test suite can even fail because of it.
-
-See https://github.com/wingo/fibers/issues/36.
-
-This fixes that.  It should be safe to destroy the peer schedulers at the given
-point because the threads that could be running them are all either dead or the
-current thread.
-
-As of May 21, 2020, this bug still existed in the 1.0.0 (latest) release and in
-git master.
