You could change the way the script handles multiple input characters:
It currently uses the "ungetstr" function, which puts keys into the low-level
keyboard input buffer and there is no method (in Baja or JavaScript) to clear
this keyboard buffer. Adding this support to the JS console object should be
trivial, so I'll have a look-see into that.
