patch 8.1.1579: dict and list could be GC'ed while displaying error
Problem: Dict and list could be GC'ed while displaying error in a timer.
(Yasuhiro Matsumoto)
Solution: Block garbage collection when executing a timer. Add
test_garbagecollect_soon(). Add "no_wait_return" to
test_override(). (closes #4571)
