Make the locking slightly smarter in Evict and add benchmark function. Seems a bit faster (there was some variance while performing these benchmarks) Master: BenchmarkCache-2 1000000 2317 ns/op 0 B/op 0 allocs/op BenchmarkCache-2 1000000 2032 ns/op 0 B/op 0 allocs/op This branch: BenchmarkCache-2 1000000 1806 ns/op 0 B/op 0 allocs/op BenchmarkCache-2 1000000 1809 ns/op 0 B/op 0 allocs/op
