	Just for fun, I started up a couple of shells... 4 to be exact.
I had three of them run the following line forever:

	echo a | cat | cat

	Since my shell uses temporary RAM files for pipes, three shells 
running the above line continuously caused files to be created and deleted 
on RAM: at a tremendous rate.

	Then, in the last shell, and while all this was running in the
other shells, I CD'd to RAM: and had it continuously get directories. 
Some of the directories came out garbled (this is using standard DOS calls
to get directories).  Every once in a while I would get a totally garbled
directory that went on forever repeating the same file entry (which was
garbled in itself).  None of this effected actual data-file creation/
deletion or storage, just the 'reading' of directories while all of that 
was going on.

	sounds like a small locking problem in RAM:.  I haven't tried it
on DF0/DF1 yet.  In anycase, it's a very-easy situation to re-create.
