Describe the bug

I am still working on understanding this issue but the test_stats_config_round_trip tests deadlock with the recently released tokio 1.52. This is hidden from delta-kernel-rs' CI because of the Cargo.lock checked into the tree pins tests at 1.51.0.

The tokio diff isn't causing anything to pop out to me.

To Reproduce

Upgrade kernel/Cargo.toml to 1.52 rather than 1.47, and run cargo test

Then wait for ...

test checkpoint::tests::test_stats_config_round_trip::json1_2_false::struct1_1_true::json2_2_false::struct2_2_false has been running for over 60 seconds
test checkpoint::tests::test_stats_config_round_trip::json1_2_false::struct1_2_false::json2_2_false::struct2_1_true has been running for over 60 seconds

Expected behavior
