1.9.0-0 is more faster in factrial test
Mandelbrot factral test (http://www.timestretch.com/FractalBenchmark.html) in 1.9.1 is more slow than 1.9.0, results:
1.9.0-0 => 2.95
1.9.1-preview1 => 4.09

Even if it is not a bug, a ticket must not be rejected as long as there is a
matter to be checked.
I tested the code on some versions of ruby.
- 1.9.0-0 0.040320 sec. (wrong result)
- 1.9.0-5 4.792150 sec.
- 1.9.1-p0 4.996654 sec.
- 1.9.1-p243 9.164635 sec.
- trunk 3.806966 sec.
1.9.0-0 output just empty lines, not mandelbrot set. It seems to be caused
by the following bug (which is already fixed on later versions):
$ ruby-1.9.0-0 -e 'v = -39/40.0; p [v, v-0.5]'
Alexandre, thank you for your report and sorry for our late response. Could
you check whether the issue is still duplicated on trunk? If so, please
reopen this ticket (or register new ticket if you cannot reopen).
