You are absolutly right.
I was confused by the name of the function (I don't use it very
often). So I thought it has something to do with the timeout in the
poll-call, which will only trigger once. Something like the
task_queues in kernel-land.

So i've learned again to always RTFM before answering.

You have also to store also the return value of gtk_timeout_add if you 
ever want to get rid of the timer.

Is there a way to add a timeout, wich is only triggered once?
If not are there any plans to put something like this in a new version 
of gtk?
