-// This test is meant to provoke a kernel bug on OSX, and to prove
-// that the workaround for it is working. It sets up two pipes and three
-// threads, the producer thread creates socketpairs and sends one of the fds
-// over pipe1 to the middleman thread. The middleman thread simply takes the fd
-// sends it over pipe2 to the consumer thread. The consumer thread writes a byte
-// to each fd it receives and then closes the pipe. The producer thread reads
-// the bytes back from each pair of pipes and make sure that everything worked.
-// This feedback mechanism makes sure that not too many file descriptors are
-// in flight at the same time. For more info on the bug, see:
-// http://crbug.com/298276
