well , if people need to use it someday it better be at some point in 
RELENG no ? 

Do you mean we will have to wait the next release ? or wait until 5.0 ?

uhmmm current.... I fear -current :)

ooops sorry :)

that would be neat yes ... i know time , time , it is everyone's problem 
on this planet :) I vote for slower earth revolution something like 
72 hours per day cycles would be nice , that with a small biological clock
tweak and a bit of genetic engineering , and off we go :)

But then again maybe we would only a 1/3 of the current lifetime :)
