No, that's not the reason why the REPL blocks I/O. The reason is simply
that at any time _either the REPL or the VM_ will run, and I/O is obviously
handled by the VM.
Also, the VM _is_ preemptive, despite the ill-named --enable-preemptive.
Semaphores (which include Delay timeouts and I/O events) can and will
preempt the running process. It is just that the VM will not preempt a
process just because it's been running for some time; that is, the VM is
not time-sharing.
