zmq.error.ZMQError: Operation cannot be accomplished in current state #110
Description
I have this issue randomly thrown at me. I am doing tests on both a x86 machine and a aarch64 raspberry pi, and it seems the issue is almost triggered 100% of the time on the raspberry pi:

zmq.error.ZMQError: Operation cannot be accomplished in current state
The code is not really relevant, as it is sometimes working, sometimes not. The error arise on a SetTransform than is ran on a separate thread from the thread that creates the meshcat.Visualizer()
Sorry for the poor bug reporting, but it is very hard to find a mwe

It's sad that this issue prevent from using callback ran in external threads to update the 3d model.
