benchmark -- accurate timing of execution



Produces an accurate timing for the code contained in the string s. The value returned is the number of seconds.
i1 : benchmark "sqrt 2p100000"

o1 = .000414609167155425

o1 : RR (of precision 53)
The snippet of code provided will be run enough times to register meaningfully on the clock, and the garbage collector will be called beforehand.

For the programmer

The object benchmark is a function closure.
