* status: new => needs_work
Comment:
With the patch, we can indeed interrupt ECL. We should try to do some more
critical stuff and see if ECL can get in an inconsistent state due to this
(I expect it can). Example session:
{{{
sage: from sage.libs.ecl import *
sage: ecl_eval("(setf i 0)")
<ECL: 0>
sage: inf_loop=ecl_eval("(defun infinite() (loop (incf i)))")
sage: inf_loop()
KeyboardInterrupt:
sage: ecl_eval("i")
<ECL: 5337027>
sage: ecl_eval("(infinite)")
KeyboardInterrupt:
sage: ecl_eval("i")
<ECL: 15518182>
}}}
