Emacs-w3m offers a means that passes environment variables to
w3m.  To do that, add a Lisp form like the following to your
~/.emacs-w3m.el file:

(add-to-list 'w3m-command-environment '("GC_NPROCS" . "1"))

Could you try it?  If it is effective, I'll add it to emacs-w3m
as one of a default value of `w3m-command-environment' for Mac.
Or is it harmful for the system which runs with some processor
even if the value of `system-type' is `macos'?  If so, I'd like
to know the way to distinguish the MacOS systems.  Now I roughly
plan to make a change as follows:

--- w3m.el~	2007-12-20 07:46:08 +0000
+++ w3m.el	2008-01-09 01:02:17 +0000
