question about the modification of "pybind11::gil_scoped_release release"

Hi,
A few days ago, the modification of "pybind11::gil_scoped_release release;" is added to Buffer::internode_dispatch, and you guys give some comments on it. In my understanding, the modification is supposed to optimize the performance of the inference system as the other threads such as kv cache is only stucked for a moment, not forever.
Is there such a possibility that without the modification of gil release, a dispatch timeout is going to happen because of deadlock? Have you ever encountered this kind of problem?

Start by reading the change involving Buffer::internode_dispatch and the added pybind11::gil_scoped_release release. Investigate whether omitting GIL release can cause dispatch timeouts or deadlocks under the described concurrent workload. Done means a reproducible conclusion, with relevant observations or a documented explanation of the behavior.
