Since then, I have received mail from gk at kksys.mn.org (Greg Kemnitz):

Okay, this is the desperate plea to the masses...  I don't know what Greg
has, but my poor little 1MB RAM machine takes 9.5 hours to crunch the maps
through pathalias.  I have a 512K board on the way, but if I *could* get
it to 2MB (for 3 total), I KNOW that my swap space would thank me. :-)

If ANYONE can supply the details of accomplishing this, or even point me
to something archived somewhere, I will gladly let everyone know of any
successes, failures, or pitfalls of attempting this.  Ultimately, the
supply of memory boards could be virtually increased since one 2MB board
would take the place of 2 or more 512K's.

So there's my story... all responses will be greatly appreciated and
publicly acknowledged.
