This job records some of the MPS design & code changes that would be needed to permit multiple simultaneous traces.

(Currently (2006) support for multiple traces is incomplete, and only one trace exists at a time. See design/trace/#instance.limit, and TRACE_MAX.)
Analysis.grey-move: Trace 1 keeps track of grey objects by listing their segments in the greylist. Trace 2 may forward a grey-for-trace-1 object out of that segment and into a different one. Trace 1 will encounter a forwarding object (broken heart): this case is not currently handled. RHSK 2006-12-28.
