- hmm, sure? if we just want IO to halt only processes which are in a
- disk IO systemcall (as opposed to `halt _every_ process' like its now...)
- then we don't need real multithreaded filesystems yet, and i don't think
- the kernel needs much more reentrancy than now like when a process
- sleeps for tty IO. and the SCSI interrupt handler could just reset
- its in-service bit and ipl and then addroottimeout()?

- cheers
- Juergen, only thinking...
