We use a simple tcp packet relay mechanism invoked by inetd and find the
setup costs to be minimal. Contact me for further info.

Before we set about support for multiple GETs, browsers should try taking
advantage of "Accept: multipart/related" to request a document and its inlined
images with a single GET. The HTTP standard specifies how to do this now!
