 I'm thinking that, in order to create a lifedebt, you have to not 
only save the other person's life, but you must put yourself in 
danger to do so.

The two definite lifedebts we know of fit this.  James Potter put 
himself in danger (from werewolf Lupin) to rescue Snape.  Harry put 
himself in danger in the shrieking shack by jumping in front of the 
wands of two wizards about to perform the killing curse.

The other life savings we know of don't.  In PS/SS, when Snape saves 
Harry at the Quidditch match, there is no danger to Snape.
When Hermione saves Harry and Ron, she had already stepped back from 
the Devil's Snare plant.  She didn't have to reenter it to save Harry 
and Ron, and even if she had, she wouldn't have been in trouble.
In CoS, yes, Harry has to kill a big snake.  But the actual act that 
saves Ginny is the destruction of the diary.  The means of 
destruction- plunging the poisionous fang through it- is not 
inherently dangerous to Harry.
