I don't think it's possible to use UNIX signals for any purpose without
introducing subtle race conditions that are extremely hard to detect or reason
about. Is it possible to eventually eliminate our use of UNIX signals for
thread suspension, or is there just no other way to accomplish this than by
using signals?
