Haiku calls Lisp in internal hooks (via safe_call) in
gui_produce_glyphs.  It does not call redisplay itself in input
callbacks during normal exxecution.

An exception is made when control over user input is transferred to
another GUI thread as part of a popup or dialog.  xselect.c and xmenu.c
do pretty much the same thing.
