So I think that the answer is, yeah, we do that syncronously.
We do a dbus call to cgmanager to get the list of pids and try to write their
proc value.
If we fail, then we need a setuid helper for things like oxide.
So it could be that spawning that helper is part of what is causing a delay
Cut the rope (which is also oxied based) is also a big reproducer of
this bug when switching from it to somewhere else (in case you need help
with reproducing)

Agreed, from playing about with this for a while now, anything that is
using oxide (webbrowser or webapp) seems to cause a very large and
noticeable delay. Although it should be confirmed that other apps are
not susceptible to this.

In my case, I was continuously switching between Telegram and Twitter
apps (post a tweet, then switch, chat a bit, then switch, etc)...could
it have something to do with the browser? (since it's also part of the
usecase presented by the bug author)

I'm currently seeing many-seconds delay on rc-proposed r308 on
Krillin...
Not sure how I got there (yet) but when I switched from one app to
others, it was freezing for a few seconds every time...pretty annoying
:)
