Allow schedules to work in multimaster.

This change allows schedules to work in multimaster. I've had to revert to a single master config for now since 2014.1.4 (the latest EPEL version) contains this bug.

I did try this with a single master setup. It does appear to work.

The code in the develop version looks very similar and may be similarly broken.
