  Log Message:
  sheep: avoid diskfull caused by recovery process

sheep can corrupt its cluster by diskfull with recovery process. For
avoiding this problem, this patch adds a new option -F to dog cluster
format. If this command is passed during cluster formatting, every
sheep process of the cluster skips recovery if there is a possibility
of diskfull during recovery.
