I also discovered that detaching doesn't work properly; I guess we have
to send along a SIGCONT when we detach. Yep, if I manually kill -CONT
the process after I detach it wakes back up.
So yeah, possibly a reasonable alternative (although I'm not sure about
the delivery of SIGSTOP to each thread...) but it does need a bit more
love than just swapping SIGSTOP for SIGINT in child_pass_ctrlc() :)
