Yes.  It's fixed two ways:

* Add timing increases so that a node can't promote -> bid in the same
cycle, or bid and attain master faster than it can declare another node
online.

* Add resolution in the case that, despite our best efforts,
multi-master occurs *anyway* - due to, perhaps, slow I/O on one node but
fast I/O on another (an unlikely case, but no doubt possible).

I think it should be beta soon, and when it does go beta, it should
appear on RHN.

The most recent fixes are not included.  Would you like me to build a
new one?
