I guess I'm seeing something similar, running on a TTY.

I'm just typing something and Emacs "gets stuck", not reacting to key
presses anymore. Every time I interrupt it in LLDB, I see that it is
somewhere in command_loop_1, wait_reading_process_input, thread_select
and so on, but it's not doing anything.

Not sure how, but sometimes at least C-g several times seems to get
things going again after some tries. And sometimes it gets going again
by itself? Not sure. Not reproducible at will, alas.
