start_zeo_server(): Read 1024 bytes from the initial connection to the

admin address of the subprocess.  Better to gulp 'em now than sip 'em
later.

shutdown_zeo_server(): Same thing here, but notice that on Windows,
the recv() can raise an ECONNRESET, which I believe we can just
ignore.  (Will test this with Tim shortly.)
