The question you need to answere is whether the signal is queued/pended 
when the target thread is not in a syscall. The behavior varies by OS, 
Linux and macOS are very different for example. None of the mails so far 
have been clear on what the behavior is on AIX so the proposed change 
may have the timing bug.
