Mysterious runtime deadlock

[alexcrichton]

I have found that this command will eventually deadlock (no schedulers making progress)

for i in {1..1000}; do; RUST_TEST_TASKS=1 ./x86_64-apple-darwin/stage2/test/stdtest-x86_64-apple-darwin multiple_connect_serial_ip6 || break; done

Still doing investigation, but wanted to open an issue on it.

This was my own problem, nothing to worry about.
