  Log:
  When breaking up a large request into smaller ones for the strategy
  routine, create all the child bio objects before starting the
  requests, rather than starting them as created. This closes a race
  whereby some number of child operations could complete before the
  rest were ever created, and prematurely freeing the parent bio.
  This fixes the panics installing in VMWare and qemu
