Douglas Katzman f16af319fa Speed up FINALIZE and CANCEL-FINALIZATION w/ many threads ... This replaces the usual hash-table with a new storage representation that is almost always lockfree, and removes all complexity around assigning a unique ID to each finalized object. The ugly hack in cull_weak_hash_table_bucket() is no more. As the benchmark shows, with 4 threads we can create finalizers about 3x faster at the cost of about 1.5x more memory. Fixes lp#1998064 where finalizers are concerned, but if the bug exists more generally, this doesn't do anything for it.		2023-01-15 22:55:05 -05:00
