It would, if the minibuffer was the only place where the keyboard was read.
However, isn't this problem wider than just the minibuffer?

In my tests with ‘sit-for’ and threads, I noticed that if multiple threads
do ‘sit-for’ at the same time, and a press a key, then only one of the
threads gets released. As you keep generating input, more and more of the
threads exit the call to ‘sit-for’. A central input processing thread would
fix this issue too, right?

Is this related to the messy event loop in GTK Emacs that people were
commenting on in some other thread recently?
