Mostly because I've glossed over the exact details of what I'm doing.  The 
table in question is a reporting table storing a list of IDs (multiple per 
key) and things like purge time etc.  When the reporting script runs, it 
needs to deal with rows that haven't been dealt with before, but not with 
rows that are currently being processed by another reporting script that's 
already processing rows not dealt with before.

In theory, no two scripts should ever access the table at the same time - they 
run 15 minutes apart.  However, I'd rather not leave it to chance.
