A question about moving GC

[Unknown W. Brackets]

But what if I don't know where the foreign code is holding it?  The C 
library might not expose this, and then I'm out of luck... unless I can 
modify it, which I probably can't.

But, this is all theoretical anyway.  I can't even think of a library 
that keeps a pointer I give it.
