Querying Garbage Collector State

--------------------------------

The C-API provides the following interface for querying information about
237+
the garbage collector.

If new objects are (de)allocated by the callback it is undefined if they
246+
will be visited.
247+
248+
Garbage collection is disabled during operation. Explicitly running a collection
249+
in the callback may lead to undefined behaviour e.g. visiting the same objects
250+
multiple times or not at all.
