Actually [speaking from experience] the Domain/OS model has its own
problems -- when your disk is full, you're also out of swap space;
when you're out of swap space, your disk is full... having these two
resource exhaustion disasters inevitably synchronized makes having a
full disk an, umm, "exciting" experience.

You really need some sort of hard limit on how much space on your disk
partition can be consumed by dynamicly-allocated swap space and "real"
file space; HP-UX "file system swap" does something like this.
