I'm using the precompiled version of SBCL/Win32 from SourceForge. I'm not 
sure how it was compiled. 

The foreign object is allocated by an external library (OpenRM) and is 
deallocated by that same library. I'm trying to cancel finalization of the 
wrapper SBCL object that references the foreign object - but from within a 
callback. Cancelling finalization of the SBCL object is successful when not 
peformed from within a callback.
