# Here's part of its definition. As you can see, it usually calls itself inside a #start block

# ```
# def request(req, body = nil, &block)
# unless started?
# start {
# req['connection'] ||= 'close'
# return request(req, body, &block) # <- request will be called for the second time from the first call
# }
# end
# # .....
# end
# ```
#
# So we're only instrumenting request when `Net::HTTP` is already started
