In "the transputer instruction set - a compiler writers' guide."
document, it states (page 30) :

> To minimise the time taken for an interrupting priority 0 process
> to start executing the following instructions are interruptable
> ...[follows a list of only 6 instructions]

What does it actually mean ? 
Does a high priority process waiting for a timer input resume execution
immediately or should it wait for the current low priority process to
execute one of those 6 instructions ???

In fact, a friend of mine interested on real-time applications with
transputers did some experiences and it seems to behave as it should,
that is immediate resuming of the high priority process when the timer
reachs the programmed delay.

Did anyone else out there find this problem ?
