that does not make use of finalizers?
I'm pretty sure that it won't. The only overhead is that the weak pointer
struct now has an extra field for a C finalizer and the code that goes
through dead weak pointers and schedules existing Haskell finalizers has
an extra if statement to check for C finalizers and run them immediately.
