I think I had to deal with that kind of things one or two years ago,
with garbage collection of SingularElement, if I recall correctly.
It makes me wonder: Shouldn't certain basic pexpect methods (such as, in
particular, _eval_line) set an attribute to self that prevents any other
attempts to call a second _eval_line before the first is finished? Such
as
def _eval_line(self,...):
if self.locked:
raise RuntimeError, "%s is locked - preventing a nested call"%self
self.locked=True
try:
<do whatever _eval_line does now>
finally:
self.locked=False
I think that would prevent the problem of nested calls during garbage
collection for good.
Cheers,
Simon
