  Log Message:
  -----------
  Client disconnect errors are now transient errors.  When
  applications retry jobs that raise transient errors, jobs (e.g. web
  requests) with disconnect errors will be retried. Together with
  blocking synchronous ZEO server calls for a limited time while
  disconnected, this change should allow brief disconnections due to
  server restart to avoid generating client-visible errors (e.g. 500
  web responses).
