Not sure I understand: you want to launch a timer from C?  And you
want to have its function to do nothing but sit-for, or something
similar?  That doesn't sound like very clean to me, but maybe I'm
missing something.

I think adding simple logic in the wait_reading_process_output loop to
reduce the timeout for 'pselect', that I suggested in my previous
message to this thread is simpler and cleaner.
