Sam Gross 6ea4f842fb [3.14] gh-144438: Fix false sharing between QSBR and tlbc_index (gh-144554) (#144923) ... Align the QSBR thread state array to a 64-byte cache line boundary and add padding at the end of _PyThreadStateImpl. Depending on heap layout, the QSBR array could end up sharing a cache line with a thread's tlbc_index, causing QSBR quiescent state updates to contend with reads of tlbc_index in RESUME_CHECK. This is sensitive to earlier allocations during interpreter init and can appear or disappear with seemingly unrelated changes. Either change alone is sufficient to fix the specific issue, but both are worthwhile to avoid similar problems in the future. (cherry picked from commit 6577d870b0)		2026-03-31 19:20:24 +00:00
