Summary: Lisp error in test suite script causes run_testsuite to hang

Initial Comment:
If there is a Lisp error in a test suite script, then
run_testsuite() prints the time and gc message and then
hangs -- anything I type is ignored and ctrl-C doesn't
get the interpreter's attention.

My guess is that the Lisp error is caught in a way that
precludes further progress. (I guess that's obvious,
sorry that I don't have anything more useful to say.)

I've found the follow can trigger this behavior:

  (%i1) defrule (a, b, c);
  (%o1)                      a : b -> c
  (%i2) run_testsuite ();

  Running tests in rtest1.mac: 28/28 tests passed.
  Running tests in rtest1a.mac: 23/23 tests passed.
  Running tests in rtest2.mac: 
  Real time: 11.429437 sec.
  Run time: 11.42 sec.
  Space: 30141840 Bytes
  GC: 14, GC time: 2.76 sec.

defrule (a, b, c)  (all atoms) constructs a rule that
confuses kill(); try "defrule (a,b,c); kill(rules)"
which yields "$B is not of type LIST". I'll enter a
separate bug report for that.

rtest2.mac contains "kill(a)" which attempts to kill
the erroneously-constructed rule a, throwing the Lisp
error.
