This may in fact be bugzillable (now there is a new word....).

But the original issue of needing to hit return is simply that the
"prompt" is overwritten by the "console" messages generated when
services are starting and stopping.  So your hitting return displays a
new prompt...  The challenge, of course, being that the services are
outside the running shell process so the shell is unaware of needing to
redisplay its prompt.

Now, my other thought on the new problem is this....

1) You are on tty1 (a text based virtual console), logged in as root,
typing in init 3.  If you are in a "window" inside of the GUI/X, then
the blank screen is entirely appropriate - you are still on tty7 but
there is no running process attached to it to display something to you.
2) The screen goes blank?  Or do you still see the init 3 command that
you typed in?  If it is truly going blank, I think you may again be
switched to tty7 without you pressing the keys.  Perhaps the death of X
causes the tty switch much like the start of prefdm/X causes us to
switch to tty7 when we boot.  If this is the case, I am not sure if this
is a bug or perhaps just a feature.... <big grin>
