Updated profiling. git-annex find is now ByteString end-to-end!
Note the massive reduction in alloc, and improved runtime.
Wed Dec 11 14:41 2019 Time and Allocation Profiling Report (Final)
git-annex +RTS -p -RTS find
total time = 1.51 secs (1515 ticks @ 1000 us, 1 processor)
total alloc = 608,475,328 bytes (excludes profiling overheads)
