> For my own understanding, could you give some insight into the ordering comments and the `spin_loop_hint`? loop hint is for waiting on the cpu without os intervention to wait until to the point of expected value for this test. > Note that this PR does no modify the ALLOCATIONS bit.

That was added in 2.0 and in the context of FFI; I measured no performance difference (maybe 2-3%). > The change set of this PR is essentially bf1a7eb I've just seen this, probably I wasn't the reviewer or simply missed the review cycle. I don't think that it can be seen in test execution. But it can be seen in the normal execution of the code. Moreover, in the actual release code, it is not needed and can be filtered out. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
