I don't see how it can be done "competently".  To my mind, interrupts are 
the lesser of two evil approaches.  If you remove interrupts, thus vastly 
simplifying the (relatively tiny but important) task of task switching, 
and also simplifying the models that describe inter-process 
communication, you instead burden *every* piece of code on the system, 
written by even the newbiest of application coders with the requirement 
that no code path exceed N-microseconds between system calls, for some 
smallish N.  That becomes essentially impossible for anything both tight 
and scaleable, like memory copy functions or FFT functions, where the 
requirement turns into a need to explicitly tesselate loops: turning 
every singly-nested loop into a doubly-nested one, with a yield() call of 
some sort tacked into the second-to-inner loop.  Now, it often happens 
that highly optimised code for these sorts of tasks *will* be of that 
form already, for reasons of cache-blocking and what-not.  But naiive 
code won't, in general, and that then becomes your limiting factor.  Is 
it better to have your system limited by the most naiive code it has to 
run, or by it's most competently written kernels?

We've all seen how well cooperatively multi-tasked operating systems 
worked.  They worked "fine" for a while, while all of the applications 
were written by the designers and other experts, and while expectations 
of performance by users were low.  In the end, the only way to deal with 
them is to throw them against a wall and replace them with a competently-
written genuine time-sharing system.

But at least the interrupt handlers generally only have to be written by 
people who are up to the task, and who understand the issues.
