Implementation of crc32 with hardware acceleration where applicable. Over 9000 downloads per day. Exposed to untrusted input through a zillion of compression/decompression libraries. Contains unsafe code around CPU feature detection and use of unsafe SIMD intrinsics.
Quick glance shows it to be fine, I'll sit down and look carefully later today
