Implementation of ruby 1.9.3 and Later
summary
Implementation notes for Ruby 1.9.3 focus on runtime and tooling rather than language syntax: a new scheduler reduces idle wakeups and cuts desktop power by about 0.3 W; a file-descriptor helper (rbfdp) fixes descriptor leaks when closing all fds; research tools include a real-time Lprof profiler and a pragmatic compiler pipeline that shows up to 80x microbenchmark speedups and ~30x gains in some cases; a MVM (multiple VMs in one process) prototype provides lightweight string transfer and scales on 24 cores compared with processes.
