Capturing the client's output tests both client and server, which is
nice. However, player input isn't visible in the resulting file,
which makes it more difficult to understand.
Route player output to journal (econfig key "keep_journal 2"), and
ignore client output.
Separate tests for the client would be useful.

connect until it works. Hangs if the server doesn't complete startup
for some reason. Make it give up after 5s.
Likewise, The smoke test waits for the server to terminate by trying
kill -0 until it fails. Hangs if the server doesn't terminate. Make
