Title: remove nextTick delay for GET, HEAD, DELETE

Since GET, HEAD, and DELETE requests do not have
a body, we can remove the process.nextTick delay
before starting the request.

The delay is there to allow content to be
piped in, but is not necessary for these
types of requests

This improves performance by roughly ~20% in
some simple benchmarks.
