That's right.  Pathalias needs a lot of memory and expects it to be contiguous.
steve@nuchat was running it on a 286 with, I think, some hacks he did to
implement quasi-virtual memory through the disk.  It took like eight hours
to run the maps for North America alone.

A 386 can handle the job, no problem.  'sugar' can crunch the maps in about
five minutes...
