/*
Wait waits until the wrapped command exits.  It can be passed an optional timeout.
If the command does not exit within the timeout, Wait will trigger a test failure.

Wait returns the session, making it possible to chain:

	session.Wait().Out.Contents()

will wait for the command to exit then return the entirety of Out's contents.

Wait uses eventually under the hood and accepts the same timeout/polling intervals that eventually does.
