So turns out that the difference seems to be that between p110 and p114. 
compiler options were maybe 0.2s difference.

Some interesting benchmarks:

p110
5.4s

p111
5.23s

p114
4.1s

latest stable snapshot from the ruby-lang page:
5.8s

[latest snapshot build doesn't run since it appears to be based on 1.9 
(?) ]

Anybody have any idea what might going on here?  All compiled similarly, 
p114 seems to smoke the rest.

Thanks.
