sudo privileges should die faster

[josé ángel madrid gómez]

Sometimes it's an advantage, but this little advantage is a bit scary
I'm talking about sudo, which is necessary to use some applications, or
to run some commands. In both cases, you can type another command, or
another app with sudo and it doesn't ask for the password. I think that
this is like that because it has a 'living time'. If the command is
launched before sudo has died, you get root permissions.
Isn't it a bit dangerous?
