Re: pause(.01) gives a mean pause of 0.0102 and not 0.0100 seconds

Note that executing tic/toc two times in a row gives interesting results:

>> t = tic; tic, toc, toc(t)

Elapsed time is 8.10623e-06 seconds.
Elapsed time is 0.000210047 seconds.

The outside tic toc (the one with sth executed inside) is about 1/5 of a ms 
(~26 times the first tic/toc), which is similar to added value to 0.01 here:

>> tic, pause(0.01), toc
Elapsed time is 0.0102508 seconds.

So it seems part of it comes from pause and part of it is internal to octave 
irrespective of pause
