OK, I like it... but can't we remove the ugly "int clear_code" arg?

The flag clear_code controls what happens if a ptrace_stop does not
stop.  In particular clear_code means do not continue with
a signal if we can not stop.

For do_jobctl_trap calling ptrace_stop it clearly does not matter.

For ptrace_signal it would be a change in behavior, that would
cause the signal not to be delivered.

Well I meant that "clear_code" should be false, iirc only
ptrace_report_syscall() should be updated to void the spurious
send_sig() if debugger exits... Nevermind, pleasee forget, this is
not as trivial as I thought.
