How do you then generally distinguish between one user running multiple
sessions at the same time detached from a tty?  On the same tty?
Seems like you need some way of associating parent and child processes.

The easiest way may be use utilise unused bits in the ac_flag field of the
accounting record.  You may need to write a syscall to do this, and you may
also need to revector the fork() system call to be able to propogate this
information to subprocesses.

Looking at risc/os, there doesn't seem to be many spare bits in ac_flag.
Maybe exit can be revectored and extra info written somewhere ? Off course,
storing this extra info before exit should also be interesting.

Also, how do you charge for the parent shell ? time based split, exec on
new project ?
