1) Re: dmclain, "MySQL will do extra work to allow you to do text-style searching on [a TEXT
column]."
Absolutely not so, unless you ask for an index.
2) to anyone implementing garbage collection with SQL DELETE, this is going to be *much* more
efficient if you add an index on the 'expire' timestamp column (which allows the
comparison to efficiently find rows).
