Guest Accounts & KeepAlive 3.3

I am not sure if this is by design or not, but I have noticed since upgrading to 3.3 I have over 1500 guest accounts. The site usually has around 50 at a given time. Well being curious I started to look at a good handful of the guest accounts and noticed the last page visited by each was the KeepAlive index page. So I looked at creation times and they are 1 minute apart. Anyone have a clue what was changed from 3.2 to 3.3 causing this?

You're absolutely right. Thanks a lot for reporting. Here is the fix.

If you cannot apply the fix (no source code), then simply set schedule task run period to 15 minutes (900 seconds).

Andrei,
The link to this changeset is no longer valid. Can you please provide the relevant code to fix this for Version 3.3. I will not be able to upgrade to 3.4 for a little while as my site only went live on Monday.

We moved to Git from Mercurial and links were changed. Now it's changeset 57727eac435e
