Hi Jonathon,

Here's a question related to the swap space one I asked you when you were 
over here a few weeks ago.

The issue is that SDRC Ideas makes very large machine-resource demands 
that until now have been show-stoppers.

Naomi tells me that we may be getting new Suns with 128 meg of memory and
4 gig hard drives by Summer/Fall, and would like to know if they can be
configured to run Ideas. 

As of now it needs: 

	at least 200 meg of swap space

	shmmax  of 16.2 meg or more (this can be achieved by making the
        stack size, as reported by ulimit -a, be at least 12 meg (it's
        8192 K on my workstation now)

So the question is- can we set these resources to at least these
values on the new machines to let us run Ideas? Note that they have a history
of increasing requirements steadily with new releases, so I'd advise making
these at least 50% more than what they require now; thus- is 300 meg swap,
and 18 meg stack, as reported by ulimit -a, doable?).

                                          Thanks,

                                                  A.
