Oh, they're all just pretty closely related. All signal and ptrace
traps run off get_signal_to_deliver(). It is still a bit hairy but in
much better shape after cleanups which accompanied PTRACE_SEIZE and I
don't really think it'll be too difficult to extend it so that
freezing is implemented as a type of jobctl trap.

Thanks.
