The functionality of MOOs read() function can be written in-db. It has been
 done more than one way, though it's always the same concept. Suspending tasks
 can also be done in-db by means of a task scheduler. Both of these rely on a
 callback mechanism, which is inconvienient from a coding point of view, but
 made the server simpler.

I am under the impression that a future release of the server will have both
 cooperative and preemptive multitasking. This will take care of the pain of
 writing and using a task scheduler. Since read() is simply a matter of
 re-directing input to a buffer until N lines are read or some other condition
 is met, I doubt writing a read() builtin is on the top of the request list.

We thank you for your interest. :)
