Compound this issue with not being able to disable spotlight indexing of time machine backups on a NAS. Often I find mds is indexing for 4-6 hours at a time, using 20-40% cpu, with no way to stop or disable it (aside from disabling time machine). Its a real shame that Apple is allowing a growing list of paper cuts to fester on an otherwise pretty solid os (looking at you thunderbolt display kernel panics, unreliable external display support, etc).
