Hmm, what for? How? What are you serving out of?

The problem is the existing http and ftp servers use file producers to serve
content, and the framework assumes producers don't block. There is no way to
make a producer that does I/O _inside_ the Medusa async framework, at least
not without using my ready() patch. The proper way to fix this is to change
the ftp and http server so they don't use file producers, instead they use
file dispatchers to push async data onto the http/ftp dispatcher.
