Hello folks,

although there is some spam in console, the impact is not noticeable at all.
Maybe if you have an ancient/crappy hardware (single core CPU).

I just checked myself.

The agent has a thread that periodically checks if the b.net launcher is still
alive (4 secs).
Since it's not the launcher or any game process that polls here using WMI, they
can't be affected.

FIXME's are in many cases not bugs.
You can always silence FIXME's on your own.
Although timeout parameter support could be implemented it's *not* required for
the apps/games to work.

A short-term "fix" would be a "once" FIXME if it bothers you.
