ps -T doesn't really work if you have any filters. so ps -AT is fine,
but ps -p <chrome pid> -T only shows the main thread.

why? because slots[SLOT_pid] is "wrong" in shared_match_process (where
by wrong i mean "is the tid").

why? because toybox reads (say) /proc/147047/task/147058/stat and sees

147058 (CompositorTileW) S 31782 6249 6249 0 -1 1077952576 4 0 0 0 0 0

and copies 147058 into SLOT_pid because that code no longer knows the real pid.

not sure how best to fix this.
