Patch at: 

https://github.com/ruby/ruby/pull/1801 

require 'memory_profiler'

MemoryProfiler.report do
  require 'uri'
end.pretty_print

Before:

Total allocated: 986643 bytes (15159 objects)
Total retained:  246370 bytes (2532 objects)

After: 

Total allocated: 926903 bytes (13665 objects)
Total retained:  208570 bytes (1587 objects)

--- 

Quite a significant change, almost 1000 less RVALUEs around when you require 'uri' which almost every web app does.
