convert to async I/O?

This could reduce latency and server load. Note @philbudne did an initial pass at trying this out here:

My thought was that it {c,w,sh}ould avoid the need to run zillions of news-search-api threads/processes to service requests from mcweb (currently 1041 mcweb.wsgi processes running with 35843 total threads)
