Benchmarks show that at certain write sizes range lock/unlock take not so much time as extra memory copy. The exact threshold is not obvious due to other overheads, but it is definitely lower than ~63KB used before. Make it configurable, defaulting at 7.5KB, that is 8KB of nearest malloc() size minus itx and lr structs.
