Pippin:

Voldemort couldn't have counted on Harry falling asleep in the middle
of his History of Magic exam.  But he could count on Harry falling
asleep at night.  If the vision had come at night, Harry would have 
talked to his friends first, they'd have come up with a plan of action
that didn't involve teachers, and no one, Snape included, would
have known what happened until the next morning. Voldemort
could blame his own impatience for ruining his plan, not that it
would be in character.  But it's already been pointed out that 
Voldemort had no reason to think there weren't  other teachers 
who were Order members. It might even be so.  Flitwick 
might have been an Order member all along. 

But someone had to tell Kreacher when the vision had got through
so that he could wound Buckbeak, That information must have come from 
Voldemort's end since Snape didn't even know about it until after
Harry had talked to Kreacher. 

I'm sure that JKR has her reasons for not letting us know how 
Kreacher and Voldemort were communicating.
But there are those mirrors which wouldn't have been as
useful as we might think. Is that because Kreacher had stolen
Sirius's mirror and Voldemort had another? 

I doubt that Voldemort actually trusts Snape. Psychopaths are
psychologically incapable of trusting anyone, and the more 
powerful Snape becomes, the more Voldemort will fear 
losing control of him.

But he does not have to be in a hurry to eliminate Snape. As
long as none of his followers  suppose that Snape has
betrayed their master and is getting away with it,  LV can take
his time and plot the elaborate sort of revenge which he
enjoys.
