Agreed. Just for fun here's a simple example of what could be an honest
mistake
that consumes all physical memory and swap. A well behaved kernel will kill
the
process eventually when it can no longer allocate memory, but not before
bringing the machine to its knees:
class Foo(object):
def __init__(self):
self.x = 1
def __iter__(self):
return self
def next(self):
self.x += 1
# Oops. In a well behaved iterator this should eventually
# raise 'StopIteration'. I knew I forgot something.
a = Foo()
b = list(a)
