Possible deadlock in concurrent write test

[RoloEdits]

Summary

I was rewriting the write command and in the process of testing I noticed that these two tests always seem to timeout. I've never seen it run fully in the times I've been testing locally. I see that it passes in CI, so I wonder if this is spurious behavior and perhaps only triggered on faster hardware?

test test::commands::write::test_buffer_close_concurrent has been running for over 60 seconds
test test::commands::write::test_write_concurrent has been running for over 60 seconds
