[Haskell-cafe] Garbage collection and finalizer thread priority

My space problems continued... :)
I have some ForeignPtr's, with finalizers (finalizerFree only). And I
have lazyly produced list of those (yes, there is some unsafePerformIO
magic behind, but I think I got this right). The problem is I get
out-of-memory condition because elements get produced faster than those
consumed are garbage collected.
list = ...
mapM_ writeOut list
writeOut :: Ptr Word8
writeOut dat = do
hPutBuh handle dat 1024
-- Control.Concurrent.threadDelay 1000
Uncommenting this line allows gc thread to run finalizers, memory gets
freed, everything runs smoothly...
As far as I know finalizers are run in separate thread. How do I
increase priority of this thread so it runs faster?
