Yeah, the existing way of sizing them is very bad on large systems
and hardcoding a size sucks (though that's what we do on large
Altix systems now).
IIRC there was some talk about using a different data structure
here - something that wouldn't require a fixed size and that
could maintain reasonably fast lookup even when it got large.
Robert, has work been done to use TRASH to address this problem?
Other ideas?
