I indeed see that with the patch, igc-collect and/or deleting the
processes (in the list-processes display) makes the number of
PVEC_PROCESS objects go down, whereas without the patch it stays at
the same value it had before (and goes up when I invoke eww for
another HTTPS connection).  However, even with the patch, the number
never goes back to zero, only to 1.  Don't know if it's important or
not.

Anyway, the patch seems to be TRT, thanks.
