It turns out to depend a little on what you did before the ^C^C and 
possibly on the version because they do different things during startup, 
which may reserve more or less stack.  I've made a couple of 
improvements.  e(xit) should now generally work.  Aborting a toplevel 
read using readline now works too (I think reliably).  Still, only
use ^C^C to force an interrupt if there is nothing else to safe the
system.

Thanks for the feedback and work to test versions.

P.s.	Uploaded 6.6.4 binary for MacOSX as the 6.6.3 was rather
	broken.  The rest will hopefully follow tomorrow.
