Summary: pres. module attempts to read (almost) entire watchers table

Initial Comment:
Hi,

The 'msg_watchers_clean()' function queries the 'watchers' table for subscriptions older than 24 hours that are still pending and then, if there are any, deletes them. Two issues:

1 - why bother with the first query at all -- why not just the issue the delete and let the back-end database deal with a possible empty set?

2 - the pa_dbf.query() for this omits the second clause in the query, so that *all* subscriptions older than 24 hours are retrieved. This table gets huge, and so after a while, this function fails to allocate enough memory to complete the query.

The attached trivial patch fixes the problem.
