Well, it would be better than using a file system synchronously, but I

It's pretty easy. After creating a partition (say, hda12), and making
it writable for the user(s) that should use it ("chgrp forth /dev/hda12;
chmod g+w /dev/hda12" or somesuch), start Gforth and say
USE /dev/hda12
Then you should be able to use the blocks from that device.
