It should run, in separate thread or not, it doesn't matter here.
Any ideas why doesn't it work?
Hopefully the GHC folk will correct me if I'm wrong but I think what happens
is:

Thanks, it worked. This is ok for me, because my finalizer only closes
some handles. Those are closed at program end anyway, so in this case I
can live with it.

I don't see why GHC can't have a 'callAllOutstandingFinalizers' call
as part of _exit() or something...

You create a FunPtr using foreign import:
foreign import ccall malloc.h free free_ptr :: FunPtr (Ptr a - IO ())
foreign
BUT: This can make some people unhappy. Isn't there a more deterministic
way to schedule finalizers?
I wrote the Hugs version which does try to be more deterministic so I'm
probably not the best qualified to write about what's wrong with GHC :-)
But, I think part of the problem is that GHC

You can do that if your finalizers are written in C (and don't call back into
Haskell) but if they are written in Haskell then you
