It sounds good enough, but I'd worry about people using this in
incompletely-thought-out benchmarking scripts.
A SAPI which supports the request time record would appear to take slightly
longer than a SAPI which does not (the time between processing the request
in the web server and passing off to PHP {plus compile, plus execute down to
that instructuion})

Do <emphasis>NOT</emphasis> use this method for benchmarking between
different webservers, inconsistent implementations could give unexpected
results.
