consing with +

[Mark.Perlin@J.GP.CS.CMU.EDU]

Since + has &rest arguments, it may entail consing.  I'm certainly getting
enough garbage collection in inner numerical loops to suggest this.
Questions:

(1) Does +, indeed, entail consing?  (If not, then DOTIMES must be the
culprit, which is even less likely.) 

(2) If (1) is true, is there any way to force + to be a nonconsing binary
operator? 

Thanks- Mark
