To activate a "daemon" for optimal storage allocation in maclisp,
(a classic as described in AI Working Paper number 14.), do
LOAD("GCDEMN");

Purpose: To run out of all spaces at the same time, i.e. to not be
 limited by the size of any one space, but to not garbage collect too
 much due to over-cautious allocation.
Idea: From storage usage patterns it predicts what future usage will be.
Bugs: Can't predict loading of compiled code, may make bad predictions under
 some conditions. Takes up a little space itself.
Recommendations: Try it when you run out of FLONUM space while making
 PLOTS, or BIGNUM space when hacking large expressions.
 Use multics or Lispm if available.
