Actually, I was referring to this
http://lkml.indiana.edu/hypermail/linux/kernel/1001.1/01120.html
from earlier (Monday) in this same discussion.  But I'll be sure to
include pointers in the future.

For more thoughts on this approach, see
http://sourceware.org/bugzilla/show_bug.cgi?id=5509
(And no, I don't expect you to have seen that before. :-))  Most of the
troublesome issues mentioned in that enhancement request have since been
resolved.
