Heungsub Lee sublee

This gist demonstrates the problems (a deadlock and a recursion limit error) due to pytorch#18566. Both code are tested with PyTorch 1.0.1.post2.

Each code has a docstring to explain itself.

Keybase proof

I hereby claim:

I am sublee on github.
I am sublee (https://keybase.io/sublee) on keybase.
I have a public key whose fingerprint is 7090 EB35 4739 3408 6E1D C7F9 2C44 EF7E 9911 31AC

To claim this, I am signing this object:

When I ignore GreenletExit during getting foo, getting bar on the same greenlet returns the result of foo instead of bar. It's a critical issue because we could not believe the result of any operations.

This example reproduces the case of "wrong callback". I tested this with couchbase-2.8.0. But I've been experiencing the issue from long time ago.

	# Couchbase 5.0.0 "edit-to-free" Security Bug
	# ===========================================
	#
	# Couchbase 5 introduced RBAC. So clients always have to provide an
	# authentication to use access on any bucket. But in case of the 'default'
	# bucket, if we edit the bucket once, clients can access without
	# authentication.
