I've seen some similar ideas from the C++ community for a number of years,
so I think Jon's suggestions have merit. There are a number of collectors,
of various levels of transparency, which can be accessed from
http://stork.ukc.ac.uk/computer_science/Html/Jones/gc.html
one of them, Cmm (ftp://ftp.di.unipi.it/pub/project/posso/cmm/) seems to
be similar to what Jon is describing for Ada. There are also proposals on
how to make C++ "GC friendly" without changing it too much; since Ada is
similar some of the same considerations apply.
