normal-gc
resets various internal parameters that determine the frequency and extent of garbage collection to their default settings.
normal-gc
is generally used in conjunction with avoid-gc, to cancel the effects of the latter.
Note:
normal-gc
is useful only in 32-bit LispWorks. In 64-bit implementations it does nothing and simply returns nil.
