After playing around with the daemon I agree that it plays a 
little too loose with processes to make this upstream material ATM 
(groups? shepherd? *shrug*).

To close:

Re-reading this I wonder if you misread SIGSTOP as SIGTSTP?  The 
two are not related.  SIGSTOP cannot be handled or blocked.

It's possible to *detect*, like one can detect almost anything 
because, but you'd be going out of your way to do so.  I still 
think the concern is oddly specific & theoretical.

Build processes *could* be using rowhammer to deliberately crash 
if you're browsing Reddit, too, and who could blame them.

Kind regards,

T G-R
