I suppose the latency was reduced because the process wasn't being terminated by the kernel anymore.

Really, the title should say "PR_SET_PDEATHSIG doesn't mean what you think it means."

The man page for PR_SET_PDEATHSIG: "The parent-death signal is sent upon subsequent termination of the parent thread and also upon termination of each subreaper process"

I was hoping it was something about reducing process latency by using some obscure IOCTL call or switching the scheduler.
