Subject: svwaitup != sv start

Hi!

I found some differences between `svwaitup` logic and `sv start`:

1)  I don't see a way how to "wait until service will be up and running
    for at least X seconds". This lead to race condition error, for example
    if we have this in /service/getty-tty5/run:
        #!/bin/sh
	/etc/setfont tty5
	exit
	exec /sbin/agetty 38400 tty5 linux
    and then will run `sv start getty-tty5` a couple of times we will see
    some success and some failures.

2)  If ./finish is running now, `sv start` will report service as running,
    but this is wrong. (I've "sleep 3" in ./finish for XWindow service, to
    prevent X from restarting too fast.)

Any ideas how to use `sv start` to make it as reliable as `svwaitup` was?
