As far as I can tell, term->waitforinput() could be replaced by=20
something like term->processevents(), which would process any pending=20
events and return. Then, this would be called repeatedly by the core=20
after a select() timeout on stdin, or the equivalent functions on=20
different platforms.
Until now, nothing different from what is done currently.

Then, several *term*->processevents() could be called, for each=20
interactive terminal previously initialized. If "term" is the current=20
terminal, all the events
will be processed. Otherwise, only events like "raise" (ie "spacebar=20
pressed" in the default setting) or "close terminal" (ie "q pressed" in=20
the default setting) would be processed.

To sum up : the getc() wrapper is a loop on :
    select(...STDIN,TIMEOUT...) on Unix,  GetMessage(...) on Windows,=20
SomeEquivalent(...) on OS/2
    first_interactive_term->processevents()
    second_interactive_term->processevents()
    ...
