Detailed Description

Simple preemptive multitasking scheduler.

All voluntary and preemptive context switching happens on exit from a common interrupt (signal) dispatcher. Preemption on quantum timeout is regulated by a soft-timer. Other kinds of preemption could happen if an interrupt sends a signal to a higher priority process (but this is still unimplemented).

In the POSIX implementaiton, context switching is done by the portable SVR4 swapcontext() facility.
