It's possible, what happens is the the taskmanager is loaded as the shell
program with command.com as a program to be run in RM once the TM is
initialized, then whenever a system call occurs, the TM traps the call and
transfers the call to the real location of the driver.  (I think.)

Another problem, we'd have to write a TM which will cooperate with OD.
