Thanks to all for their replies!
I've got some great options to try now.
It also confirmed that the readline library is usually (always?) invoked in a blocking way, and that a char-by-char alternative approach is needed and even mostly done!
I figured that shells like bash somehow use readline while allowing input to flow in from other sources (eg pipes in the background etc), and without looking at the bash source I figured it would be doing this with select, not multiple threads.
Many thanks everyone, I really appreciated all your comments!
