Probably.  I'll be the first to admit that we've been working in "quickest way 
from A to B" mode, and haven't seriously enough incorporated performance 
concerns to our approach.  This might limit 4SXL's general usefulness until we 
optimize it.  I'll cache this among the growing list of "excellent Prescod 
suggestions" in our design process.

Aah, the light dawns.  And I guess this one also goes into the list of useful 
suggestions.  I like the idea a lot, and I can already forsee many useful 
applications.  The main problem will be how much effort into modifying the 
current design would be required.
