This is not correct,  at least with \os2\vdisk.sys,  which always allocates
non-swappable memory.

I released a modified version of vdisk (called swvdisk2.lzh) which does use
swapable memory,  and it works well as long as you are using a recent
fixpak.

Albert Shan wrote a new virtual disk system from the ground up,  which uses
a different technique (you can actually change the size of the disk at run
time).  It is shareware.  It is called something like "super virtual
disk".
