interactive keybinding to abort all input?

interactive keybinding to abort all input?

[Greg Klanderman]

I seem to have some problem with copying and pasting in X; sometimes
copying from emacs to my shell window results in some previous
selection getting pasted, and when that's several pages of code, it is
really a pain waiting minutes for zsh to finish trying to interpret it.

Seems like Control-C or Control-G should allow me to abort all input
but it doesn't.  Should it?  Is there some way to abort all pending
input to an interactive zsh?

thanks,
Greg

The problem is, I believe, that the input is buffered up by xterm, so
what you need is a keystroke to cause *xterm* to discard all pending
input ...

I am not sure this is zsh fault. It is entirely possible that X terminal 
is busy processing selection and starts to act on ^C only *after* entire 
buffer has been pushed to child.

OK, this (unfortunately) makes sense.. and even the xterm 'hard reset'
action does not seem to clear the input buffer, nor do any of the
signals it seems to accept.
