So, if I set --enable-maxpage=64*1024, then the default
hole size would be --enable-holepage=6*1024, right? How
small can I practically make it?

I am willing to try but I have never done this. Can you
given me a few (explicit) tips how to proceed? It is
also apparently possible for me to connect a usb disk
drive to this BIG MACHINE in the small box (: Yes, I am
very impressed by the SL-6000! :) There is a nice little
40 Gbyte drive that runs directly off the usb power for
about $200. Perhaps I will run down to the store when
it is open again tomorrow...

Maybe I should just admit that running Axiom isn't (quite)
practical on this system unless I can add swap space?
But as a continued challenge, I note that I can run Clisp
and maxima under Clisp in much less space without swap.

Well you were right. The build stopped apparently at the point
were it was about to create depsys (it built bootsys ok). See
the build log below. Does the message "Can't allocate buffer"
tell you anything specific about memory?

Yes, tomorrow.
