Spending time in PS1, was Re: [RFC/PATCH] shortstatus v1

I wonder if I could ask people opinions on a trick I pulled, which is 
basically maintain a state of the value of $SECONDS each time the user 
is shown a bash prompt.  If the value is the same as last time (meaning 
he hit enter twice in a row very quickly), it runs the extra stuff.

As you know, I am a big fan of consistency.  In this light, I do not like 
it when I am shown something at times, and at other times not.

Besides, I agree with Junio that even a single second spent to calculate 
PS1 is too much.  I use my command line extensively (some claim I live in 
it).  An slow PS1 would drive me to madness.

Ciao,
