Memory leak in Net::HTTP.get and non memory leak in HTTPClient.get which I think impacts Anemone https://github.com/NearbyFYI/anemone/blob/next/lib/anemone/http.rb#L136

gistfile1.rb

require 'net/http'

# Memory continues to climb.
idx = 0
loop do
  begin 
    # Our sample website
    url = "http://localhost:2000"
    resp = Net::HTTP.get(URI.parse(url))
    puts "run loop: #{idx}"
    idx += 1
  rescue
    # do nothing
  end
  sleep rand(0.1) # just a wait
end

gistfile2.rb

require 'nokogiri'
require 'httpclient'

# Memory use is maintained
@@http_client = HTTPClient.new
@@http_client.connect_timeout = 60
