Thanks, I'll put one in.

What feature is using the below in the idle timer?  I cannot find a call 
to semantic-symref-result-get-tags in anything that is called from the 
idle timer except for the use of gnu global as a database backend.

Even in that case, the purpose is to close buffers that weren't already 
open.  The earlier block of code in that function attempts to do that 
with get-file-buffer.  If the database return is retrieving a file name 
for which get-file-buffer fails, but find-file-noselect succeeds, well 
that's kind of interesting.  What do you think that might be?  You can 
look in the temporary buffer *CEDET Global* to see what those names 
might look like.
