Hello,
I had a realization yesterday, that our documentation misses the point
of guardians. Guardians exist to allow finalization of resources
without introducing concurrency. However if you pump a guardian from
the after-gc-hook, as recommended by "GC Hooks" in the manual, a
guardian is simply a finalizer, implemented in a roundabout way.
Food for thought!
Andy

I could have told you that. I already implement an add-finalizer! in
roundabout way using guardians :P
