[Haskell-cafe] Boxed Mutable Arrays

Is anyone working on fixing ticket #650
<http://hackage.haskell.org/trac/ghc/ticket/650>? In short, STArray
and the garbage collector don't play well together, resulting in array
updates being non-constant time operations. This bug makes it very
difficult/impossible to write efficient array algorithms that depend
upon mutation in Haskell.
On another note, does this (or perhaps better phrased, will this) bug
also affect Data Parallel Haskell?
I would really like to see highly efficient, mutable, boxed arrays in
Haskell! Unfortunately, I don't have the know-how to fix Ticket 650.
