Comment 4 for bug 363134

autoinc lockmode 1 can cause a crash with 2.0 wsrep-5.5 build with master-slave test

The crash should be fixed to begin with.

After that, there are optional strategies to deal with this:
1. Allow only lock mode2, and enhance wsrep option checking to always reject all but value 2 for autoinc lock mode
2. Allow lock modes 0 and/or 1 conditionally in master slave use case
3. Allow lock modes 0 and/or 1 always

Unfortunately it is not possible to distinguish between MS and MM topologies inside the node, so cases 2 & 3 will require some more planning
