Return #t if obj is an object in the current process, else #f.

Procedure: local-promise-refr? obj

Return #t if obj is a promise in the current process, else #f.

Procedure: local-refr? obj

Return #t if obj is an object or promise in the current process, else #f.

Procedure: remote-object-refr? obj

Return #t if obj is an object in a different process, else #f.

Procedure: remote-promise-refr? obj

Return #t if obj is a promise in a different process, else #f.

Procedure: remote-refr? obj
