This patchset seems to cause a regression for the following simple test case for me: sheep -l7 -d /tmp/sheep/7000 -p 7000 collie cluster format --copies=1 -p 7000 collie vdi create 'test-vdi' 300M -p 7000 before that is finished in about 30 seconds, now it hangs or at least takes magnitudes more time.
