Slightly off-topic, but how did Intel's 9.1 compiler fair (win and/or 
Linux)?

We've found it better for vectorisation, but may be about to embark on using 
fusion et al so wondered if you'd done any small object/inlining/templating 
tests with that too.

I've often thought having some performance tests on the regression suite 
would be good, but I can see it being problematic to factor out different 
user's and different CPUs et al.
