I'm capturing both PRESSED and CLICKED, the former being a slow click in 
practice.  I had the same idea tho, the mouse-up is dangling.  What's 
puzzling is that I can't force the error.  I can press and hold the 
button, wait for the program to end (so far mouse clicks always make a 
selection from a list and return) and then release the button and, 
again, maybe one time in 20 I'll get the bogey.  I've tried variation on 
click speed but nothing  makes it better or worse.   You don't suppose 
it could be a mechanical issue with the mouse?  You know how they 
sometimes get sticky and mouse clicks are poorly registered?  I've had 
mice that tended to return two clicks when only one was made.  A 
mechanically unclean release seems to confuse the computer.

Well, so far the 'timeout' is working 100%, still I myself would sorta 
build that in to 'zcurses end'.  While in zcurses,it owns all inputs so 
on quitting the idea that some input would be 'forwarded' to the 
terminal seems strange.  Dunno, maybe such a thing could be wanted but 
... well, could it ever be wanted?  As you say there are these 
'generated by the terminal' ... but I don't know anything about such 
things.  Seems to me the terminal receives input, not makes input but I 
suppose an xterm is itself a program that writes to hardware so ... But 
this is the only time I've ever seen ghost-writing to zle.

BTW you were right about ERR_EXIT, sheesh, it nukes the whole terminal.  
I had something like ERR_RETURN in  mind but I guess we don't have that.
