We present a new protocol for the distributed detection of garbage,
suitable for a low-level distributed object-support system.  It is
based on realistic assumptions: messages may be lost or duplicated;
sites may crash; an object may migrate or be deleted.  The protocol
uses only information local to each site, or exchanged between pairs
of sites; no global mechanism is necessary.  It is parallel and should
scale to extremely large systems.  It takes into account the
object-finding protocol.  Its interface is designed for maximum
independence from other components.

The former is a DVI file, the latter is PostScript.  The former is
smaller and (in my experience) more portable than the latter, which
has been prepared for a LaserWriter II NTX.
