[stable-2.10] Fix super annoying Python 2.6 multiprocessing.Queue stack trace in CI (#72604) (#72608)
* Fix super annoying Python 2.6 multiprocessing.Queue stack trace in CI

A bug exists in Python 2.6 that sometimes raises an exception during interpreter shutdown. We
encounter this frequently in our CI since we run tests on CentOS 6 as the control node, which
has Python 2.6.6 with this bug.

This PR adds a very minor sleep only on Python 2.6 which gets around this issue. I did lot of testing
using a standalon script I found that easily duplicated the issue to find the minimum sleep value
needed to avoid this issue.
