[Mono-list] How do I force a garbage collection / free a heap

[Chris Howie]

And note that GC.Collect() is only a recommendation to the runtime
that now might be a good time to run the GC.  The runtime is free to
ignore this call if it so chooses.

(PS Sorry about the top-post.  Gmail mobile is not the best for lists.)
