that (and filling up /tmp - or whatever LYNX_TEMP_SPACE points to)
are both possibilities.  But this is harder to check than the other.

Also, there's always the possibility of a bug that no one noticed
before.  If I had lynx hanging, I'd verify that _it_ is not stuck
by attaching it to gdb and seeing what tracebacks I'd get from
the first attach, and then (next/interrupt) if it's not in the same
area.

Lynx doesn't do much that's specific to large-file access.  The host may 
require some specific version of the stat() function (and fopen/fclose),
while lynx may need a specific formatting type to report values above the
traditional limit.
