I just wrote this, before I read you proposition: As safer alternative would be to keep a cache of pre-malloced buffers, populated by the ByteString finalizer. But the bookkeeping cost could outweight the benefit of avoiding malloc.
How are you getting these bytestrings? Normal bytestring allocation doesn't use malloc and doesn't use finalizers; it calls the (deceptively named) mallocForeignPtrBytes function, which allocates a block of data in the pinned GHC heap, nearly like any other Haskell object.
IIUC, the discussion was about malloced ByteStrings... Best regards Tomek
