I spent some more time debugging this and sigishandled() seems to be failing
for this signal 32. The preceding lines in strace output like this:

rt_sigprocmask(SIG_SETMASK, NULL, [HUP INT QUIT PIPE ALRM TERM CHLD RT_0], 8) = 0
rt_sigsuspend([HUP INT QUIT PIPE ALRM TERM CHLD] <unfinished ...>
--- SIGRT_0 (Real-time signal 0) ---

Btw, wouldn't it make sense to add a ptrace kernel option to get this
information instead of going through /proc?
