Here's the abstract:

Guardians allow programs to protect objects from deallocation by the
garbage collector and to determine which objects would otherwise
have been deallocated. When the object has associated non-memory
resources, a program can register it with a guardian. The GC will
mark inaccessible objects but will not collect them; at the
program's convenience, inaccessible objects are removed from the
guardian and their non-memory resources are disposed of. Guardians
allow objects to be saved from deallocation indefinitely so that
they can be reused or so that clean-up or other actions can be
performed using the data stored within the objects. Guardians avoid
the problems associated with classical finalizers detailed in the
Rationale section.

Regards,

SRFI Editor

There are running jobs. Why don't you go chase them?
