@RuRo, @reminisce helped point out an error in your reproducer script. You
use zero-shape tensor, but didn't enable numpy shape semantics. It should be
```
import mxnet as mx
mx.npx.set_np()
with mx.Context(mx.gpu()):
while True:
for _ in range(100):
mx_data = mx.np.array(0)
mx_x = mx.np.empty_like(mx_data)
mx.nd.waitall()
print(end='.', flush=True)
```
This explains the error in

You're right, it shouldn't cause a deadlock.
