"ignoring polymorphic case..."

[Hal Daume III]

I'm getting the

WARNING: ignoring polymorphic case in interpreted mode.
   Possibly due to strict polymorphic/functional constructor args.
   Your program may leak space unexpectedly.

warning in GHCi (5.04).  I'm used to getting this when I have a datatype
with strict arguments, but the only data type I have in this module (and
it doesn't import any of my own modules) is:

newtype GArray s key elt = GA ((STRef s (Int, STArray s Int (key, elt))))

should I be worried?
