  Log:
  MFC revision 1.181
  
          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
