booting from EXT3 would require to make EXT3 part of the kernel.
not going to happen.

otoh there is virtually no disadvantage to have a loadable TSR to make
EXT3 available as a redirector.

don't wait for multithreading support from kernel.

in the good old times, when DOS was still active, disk caching
software implemented 'multithreading' by chaining into
TIMER and IDLE interrupts.

just because so far no FreeDOS disk cache supports write caching
doesn't mean it doesn't exist
