TWO LINE PATCH, SPEED UP 2 TIMES

[[EMAIL PROTECTED]]

Hi,

  I don't know what to belive but this 2 line patch gives me a speed up 
of two times.
The output of my test program(signs 300 times the same DOM, don't be 
fool with native or Sun they are the same provider)

Before the patch:
Calentando:
12496ms (100 signs)
SUN:
10923ms (100 signs)
Native:
10706ms (100 signs)
After the patch:
Calentando:
5603ms (100 signs)
SUN:
4385ms (100 signs)
Native:
4352ms (100 signs)
More or less two times,

Please can you all test it and tellme if you see the same speed-up. It 
is very weird.
Regards,
