Tom Boucher 1868947088 perf(#316): hoist state-lock sleep buffer out of retry loop (#399) ...

acquireStateLock was allocating a fresh SharedArrayBuffer on every retry
iteration via Atomics.wait(new Int32Array(new SharedArrayBuffer(4)), ...).
The buffer is never mutated and never escapes, so hoisting it before the loop
is a provably-equivalent transformation — Atomics.wait always sees value 0
whether the buffer is fresh or reused.

Fixes #316
