That name for a file is only created with a flat_list cache backend, 
specifically when it's doing an update to an existing entry (kind of a 
duh there considering the name, I know).

The algo is roughly
f=open(tmp_update_entry)
write to it
close it
utime it (reset mtime)
rename(tmp_update_entry, update_entry) 

Hence the 'offhand'.  Don't know if it's rename or utime that's not 
defined- just know that those are the only two syscalls that could 
sanely trigger that (failed update will trigger an unlink, but I'd be 
amazed if that call was missing).
