DD's definitely dead (Snape)?

Luckdragon said (with much snipping):

 If anyone could prevent [DD's] death from the potion it was Snape, 
who if I recall correctly told his first year potion students that
"he 
could 
teach them to put a Stopper on death". 

I know this has been discussed before, and the actual quote is still 
open to interpretation, but Snape actually said "a stopper IN death". 
This makes a huge difference, because it means Snape's talking about 
bottling poison, not an antidote. "Stopper" means cork or lid,
meaning 
he could teach anyone with enough competence to make and cork death
in 
a bottle. (I'm not arguing that Snape isn't up to making antidotes, I 
agree that if anyone could do it, it would be him, but this might 
provide some insight into his motives and priorities...he chooses to 
mention his skills with poisons rather than how to counteract them-a 
clue perhaps? Who filled that basin anyway?)
