Ugh, that was a horrible commit message.
This uses the frozen string cache in Ruby 2.1.0 if available. The
frozen string cache implements the:
"literal string"f
syntax found in Ruby 2.1.0 (this Ruby syntax is not set-in-stone, but
the idea of the frozen string cache seems to be popular in ruby-core
right now and unlikely to go away).
Strings in the frozen string cache benefit from best-effort
deduplication, but can still be GC-ed (unlike Symbols). Obviously they
are strings, too, so they're usable for Rack headers.
