My experience is that the system crashes.

I have not tested this with a snapshot but a general thin pool overflow 
crashes the system.

Within half a minute, I think.

It is irrelevant whether the volumes had anything to do with the 
operation of the system; ie. some mounted volumes that you write to that 
are in no other use will crash the system.
