 Did I say that? I thought I had said that the signal might not have
 been delivered...yet. Which would explain why the OP hadn't seen
 their expected behaviour.

 So, no you can't trace yourself and thereby ignore SIGKILL.

 As it happens, SIGKILL (and presumably SIGCONT) is delivered to the
 process irrespective of tracing and debugging (and pstop and ...) so
 that part of my statement was incorrect. My apologies.

 IO is still an example of a higher priority service that must
 complete *before* a queued signal, including SIGKILL, can be
 delivered.

Cheers,
