This is a nice post and transactional memory is great! Worth noting about the particular implementation on Intel chips: In August 2014 Intel announced a bug in the TSX implementation on current steppings of Haswell, Haswell-E, Haswell-EP and early Broadwell CPUs, which resulted in disabling the TSX feature on affected CPUs via a microcode update.
