-/*
- * This is a simple API to implement pointer back tracing, i.e.
- * to answer questions such as "who is pointing to this" or
- * "why is this object being retained by the collector"
- *
- * This API assumes that we have an ANSI C compiler.
- *
- * Most of these calls yield useful information on only after
- * a garbage collection.  Usually the client will first force
- * a full collection and then gather information, preferably
- * before much intervening allocation.
- *
- * The implementation of the interface is only about 99.9999%
- * correct.  It is intended to be good enough for profiling,
- * but is not intended to be used with production code.
- *
- * Results are likely to be much more useful if all allocation is
- * accomplished through the debugging allocators.
- *
- * The implementation idea is due to A. Demers.
