Node panic on timeout while waiting for event stream thread

[haixuanTao]

Not exactly sure what is happening, but it seems that I have a bug where the node completely freeze and then report:

�[2m2024-08-30T16:15:37.258067Z�[0m �[33m WARN�[0m �[2mdora_node_api::event_stream::thread�[0m�[2m:�[0m timeout while waiting for event stream thread

Then the node finishes.

I wonder if there is like a break condition on:

dora/apis/rust/node/src/event_stream/thread.rs

Lines 70 to 72 in 9be5b76

	Err(RecvTimeoutError::Timeout) => {
	tracing::warn!("timeout while waiting for event stream thread");
	}

Before the node freeze, everything is normal.

This only happens with python by the way. Does not happen with rust dora-rerun with the exact same example.

FYI, this seems to happen when there is more than 1 listener of the camera output stream.
