How to specify thread priority?

I need to run multiple threads on an embedded-linux target. One of the threads requires a lot of resources so I need it to run in background at a low priority. There will be times when the higher priority threads will have nothing to do. A typical vala Thread.create looks like this:

Thread.create<void*> (pProcessor->run, true);

Is there a way to specify the thread priority?

You can't use the threading stuff in GLib, you would have to use pthreads directly. There is some information on how to do that in C here. You would also need to create Vala bindings for the relevant functions since nobody has done so yet (it's pretty easy... if you understand how Vala maps to C it would only take a couple minutes).

If I were you I would look into using a priority queue instead. If you don't feel like writing your own bump should already have everything you need (specifically, Semaphore and/or TaskQueue), or AsyncPriorityQueue if you would prefer to work at a lower level.
