<H2>The Parallel Marking Algorithm</h2>
We use an algorithm similar to
<A HREF="http://www.yl.is.s.u-tokyo.ac.jp/gc/">that developed by
Endo, Taura, and Yonezawa</a> at the University of Tokyo.
However, the data structures and implementation are different,
and represent a smaller change to the original collector source,
probably at the expense of extreme scalability.  Some of
the refinements they suggest, <I>e.g.</i> splitting large
objects, were also incorporated into out approach.
