endpoints client server is needlessly complex

[Jaymon]

The wsgi clients use a subprocess and thread to run the server using the endpoints.__main__ module, this seems excessive, why not just run it in a thread locally? I think that would be simpler and easier, the uwsgi makes a bit more sense since it runs uwsgi, but even there, it might be worth looking at the new testdata.command stuff that uses subprocess and threading since that codes is newer and conceptually simpler
