map every new window iconified?

I apologize if this question has been answered before,   but although I see=
 questions that dance around the topic I've never seen an answer to this

Is it possible with the current sawfish (I'm running 1.12.0) to specify tha=
t :

  EITHER     *every* new window
  OR             each window in a specified list of window-names

that is created (mapped?) starts off iconified?
If so,  how?   (some use of map-notify-hook?)

The reason is that ,  along with other posters in various lists,   I want t=
o prevent a "slow-starting" X-application from suddenly grabbing my keystro=
kes and sometimes causing damage to both my current focus and this new one.

I am a very happy sawfish user of many years and on many flavours of linux.

Cheers,   John Lumby
