Why are you worried about loss of a few UID's, the table? You can have
about 4 BILLION different UID's, if you are worried about using up all
your UIDs you site must be EXTREMELY active, and there are a number of
other things that need to be looked at well before you run out of UIDs.
(and a relatively small change in table schema can increase the limit to
virtually unlimited by changing UID to a bigint everywhere it is stored).
