Oh... but the FAQ (# 18) explicitly says "nodes + 1" and gives "3"
as the example for a two-node cluster. And I tried it (accidently)
with expected_votes="2" and the result was that the nodes started
fencing each other in an endless loop. This was solve by setting
expected_votes="3". This is on RHEL5. b.t.w., not RHEL4.
