succeeded.
After this call succeeds, the service is free to run. At some
point in the future, the SCM will send a message to the service,
requesting that it stop. This is translated into a call to
winservice_notify_stop(). The service is then responsible for
cleanly terminating.

(opening files, sockets, etc.) because the SCM wants you to
connect *first*, then do your service-specific logic. If the
service process takes too long to connect to the SCM, then the
SCM will decide that the service is busted, and will give up on
it.
