bug-1282 (ABBA iomgr deadlock) is FIXED and verified (commit 25e741d): zero
__lll_lock_wait threads post-fix, unit suite green. But a plain release soak WITH
the fix still segfaults a restarted standby at round 4 — and deadlocks hang, they
do not SIGSEGV, so that crash is a SEPARATE bug (bug-1283), most likely an
endpoint-lifetime UAF under chaotic restart (bug-1197 family).
bug-1283 is a heisenbug (invisible under ASAN and gdb; no usable core in the
sandbox) and likely UPSTREAM raft-drive-async / core libxce endpoint quiescence.
7.2 stays blocked on it. Consensus correctness (Phase-2/5.2/5.3) is unaffected.
