Okay, using 2-2-patched, I'm fine.

Using 2-3-patched and R-devel, I'm not fine (stack warnings and segfaulting).

What is the precise incantation for setting the stack?   using
"--max-ppsize=N"    didn't seem to help my problem (for values of N of
5000, 25000, 50000 -- should I try others?)

(This is under SBCL, i.e. satisfying Duncan's conjectures -- as soon
as I fix a few things (i.e. undoing CommonLispStat/R's threading which
is a bit SBCL specific, I'll try under CLISP, ECL, and CMUCL to
verify/check).
