But not I think for multi-user machines. That is 35Mb allocated (on Solaris)
and I would not want our students taking 35Mb for each R job, as the
current memory management really needs most of it resident. About half
that would be tolerable, hence my original figures.  We would like them 
to use perhaps 50Mb in total.

Also, that is too much for 64Mb Windows NT machines, and that is 
high-end for teaching labs.
