Since r58846 (in Ruby 2.5), it is safe to clear the string
yielded to Net::HTTPResponse#read_body methods. This
reduces malloc garbage (anonymous RSS) using the Linux-only
script below:
before: user system total real
0.030000 0.250000 0.280000 ( 0.280511)
RssAnon: 60240 kB
after: user system total real
0.050000 0.223333 0.273333 ( 0.273118)
RssAnon: 6676 kB

before.
Net::HTTP::Proxy still creates anonymous classes, but these classes
are only used to store configuration information. When an HTTP
instance is created the configuration is now copied.
Additionally, Net::HTTP::ProxyDelta is no longer used by Net::HTTP
