worker: use engine-provided deleter for `SharedArrayBuffer`s 2019-01-03T22:44:52+00:00 Anna Henningsen anna@addaleax.net 2019-01-01T20:42:43+00:00 1f1a373df0121a9e4a2887f69862169b2f4ed2fd Store the full information we have on a given `SharedArrayBuffer`, and use the deleter provided by the JS engine to free the memory when that is needed.
