thread_exit_signal fails intermittently

This I can reproduce locally using

bash thread_exit_signal.run -b ~/rr/rr '' &  thread_exit_signal.run -b ~/rr/rr '' & bash thread_exit_signal.run -b ~/rr/rr '' & bash thread_exit_signal.run -b ~/rr/rr '' &

Still seeing this fail intermittently:

[FATAL /data/keno/rr/src/RecordSession.cc:1232:inject_handled_signal() errno: EBADF]
 (task 74332 (rec:74332) at time 746)
 -> Assertion `t->get_signal_user_handler(sig) == t->ip()' failed to hold. Expected handler IP 0x55cc00402cfd, got 0x7fd391f01084; actual signal mask=140546659796480 (cached 140546659796480)
[FATAL /data/keno/rr/src/log.cc:289:emergency_debug() errno: SUCCESS] (session doesn't look interactive, aborting emergency debugging)

Not easily reproduced locally :-/.

I haven't seen this in a long time, so this issue is probably useless by now.
