Re: [Haskell-cafe] Garbage collection and finalizer thread priority

I presume you're running GHC. There's no way to increase the priority of a thread - GHC's scheduler doesn't have a concept of priorities.

Yes, I forgot to state it explicitly.

I would look into whether you can use mallocForeignPtr: this is much faster than using newForeignPtr with finalizerFree, because the memory is garbage collected directly and there's no need for a finalizer.

I use mallocBytes + reallocBytes + addForeignPtrFinalizer finalizerFree. I wouldn't think this is any different, thanks for your suggestion. May I ask where that difference comes from? -- Gracjan
