Yeah I was wondering too, why SCO.

One can, and maybe should, also limit the memory used.  For example
from a bash or other Bourne-ish shell, with the ulimit command.

I test that sometimes for a small value; lynx can *usually* recover
when memory becomes exhausted while loading one of several files that
are too big.  (But it also might just quit abruptly.)  There are some
checks I added a long time ago that try to detect memory exhaustion
and deal with it gracefully, in the place where it is most likely
to happen (cf. CHECK_FREE_MEM in GridText.c).
