Thanks for the info, Perry.  To use memory most efficiently, and have
the best performance, it would seem that one should:

1 - Set HighCyl in the Mountlist such that one's normal ram load just
    about fills VD0: (rather than just setting it to give the largest
    possible vdisk).

2 - Use VD0: for more or less "permanent" files, and use the normal
    RAM: device for the transient stuff (like intermediate compiler
    files, and such).
