Not one that's visible to Lisp.  Why would it be?

nil.  If a thread calls buffer-live-p, that means it's prepared to
recover if b-l-p returns nil.

I suppose you're thinking that the thread might want to snarf the data
before the memory gets reallocated or something like that, but if
other threads are killing your buffers, who knows what they might be
doing to the contents?  Better to just give up.
