All this comes back again to having several pools, showing how useful
such a primitive is.
Speaking of rethinking the GC and its primitives, is there a way
currently to tell the GC to track pointers to a manually allocated
block and assign a callback for when the GC wants that block to be
finalized and deallocated? I'm kinda going to need that if I am to
bring decent garbage-collected Objective-C objects in D.
It's coarsely grained, but you can intercept all finalization calls:

You'd have to figure out some way to filter only the ones you care about.
Also, there's an undocumented, non-published (i.e. not in object.di)
function that allows you to attach an event handler when an object is
disposed:
https://github.com/D-Programming-Language/druntime/blob/master/src/object_.d#L2394
I think Bill Baxter's WeakRef object used it. I'm not sure how supported
it is, or why it isn't public.
