Suppose we tag them with a buffer-local variable.

What if the use switches to one of these buffers on their own accord, 
with find-file or switch-to-buffer? They might not be aware that that 
buffer was opened by xref, and would be surprised to see M-x 
xref-kill-temporary-buffers kill that buffer as well.

It keeps a cache of search results (and initiates full search for any 
input not in cached list). That's nice, but probably solves a different 
problem.

Of course. But first we should try.
