re-niceing corosync should not be required as the process is supposed to run with RT-Priority anyway.

We configured the token timeout to 17 seconds:

 totem {
        transport: udpu
        rrp_mode: passive
        token:     17000

This configuration works just fine for us since months: We didn't see a single 'false positive STONITH' with this configuration.
