Well, the core buffer code is pretty much unchanged since 1.3, but
compiling tags with buffering is relatively new.  Rimon was something
of a performance nazi, so my guess is it's the compiled code's fault,
rather than the execution model, but it may be worth testing that
assumption.

In any case, you can see the difference in the generated code, both
for your page and the tag, by running spyceCompile from the command
line.  (I don't think the page code will be any different, but
I wouldn't place too much faith in my memory for that, either. :)
