Thanks for the report. This is a known problem, however,
it is hard to fix soon.
In current console implementation, ctrl-Z is processed in
read() system call. So, if process does not call read(),
ctlr-Z does not work.
You can confirm that ctrl-Z works for cat, od, etc. which
calls read().
One solution might be to introduce a thread to handle the
keystrokes. I wonder if it is worth enough to introduce such
a big modification for console code.
