Yeah, i looked at that.
And it's called a leak, isn't it? :)

I first noticed this when my recorder wouldn't record anymore,
complaining about not enough free Vmalloc left.
(My program used the wrong way to stop the recordings..)

So, after about a month of uptime, with quite some recordings,
it took about 100MB of Vmalloc.. (i have 128MB, and after booting and 
starting X etc, about 100MB are still free)

I rebooted the machine and did some testing, and came to the mentioned 
conclusions.
What i didn't really mention precisely in my first post is that the 
leaks add up, so you'll run out of Vmalloc sometime, as shown above.
