RT comes in several flavors, of which I know the SJ and FB
(foreground/background) flavors, V2 specifically. Both are unprotected
operating systems, so you can play with I/O devices at will.
Also, in those there definitely is no caching in the file system. For that
matter, the file structure is simple enough that there really isn't anything to
go "inconsistent". A crash in mid-operation might cause a file not to be there
if it was being written, but that's about it. The only exception I can think
of is the file system defrag operation, but then again that one may be written
in a fault tolerant manner, I don't know.
