Hey Greg,

Sorry for the late answer, this got lost in my inbox for a while.

I added the API to do those kind of things upstream in Qt 5.15:

However, I didn't get around to actually implementing something to e.g.
show the PID inside qutebrowser - currently tracked here:

Right now, the easiest thing you can do is to send a SIGSTP to the
process and see which tab is frozen; or send a SIGTERM and see which tab

Also, @toofar wrote a slightly crazy script to find the offending tab
