More precisely:

It's a decent amount of run-time memory if yr running hard expressions
and want optimal performance.  You can limit run-time allocation
pretty low (a couple 10K) and get _ok_ performance and great
correctness (and good performance on very simple expressions).
Basically, the space/time trade-off is reduced to a parameter that you
can tweak at run-time.
