It's probably worth investigating where the time is going, or actually measuring the time (even 'time make test') to make sure this isn't a real regression. This really isn't the hot path in the analyzer, so 1 second would be possibly a big deal.
Well, any changes to evalCall are in the hot path, even if they're doing the same work before and after.
I ran 'time TESTDIRS=Analysis make test' a couple times before and after the change, and while the usertime average does seem to have gone up by a second or two, the error margin is something like 10s just with Mail.app running in the background. So never mind.
