By default GCL will start gc at 1/2 physical memory, then progressively
increase aggressivity to maximum at 3/4.  The parameters are all
adjustable with environment variable settings.

Glad to see this feature is getting some exercise, as I think it needs
to be turned on by default at release.  There is a small overhead which
I regret, but communicating to multi-instance users how to setup their
environment seems to forbidding an alternative.

Thanks for all your work on maxima!

Take care,
