    MBUF - Do not limit an objcache common pool to 10 magazines.
    
    * An objcache's common magazine pool was limited to 10 in order to return
      memory to the system sooner rather then later.
    
      This created a situation with the mbuf allocator where high-rate
      mbuf producers (GigE, 10GigE) would sometimes not be able to allocate
      a large enough batch of mbufs and drop packets.  10 magazines x 64 is
      only 640 mbufs.
    
    * Increase the limit from 10 to 1000.
    
    Tested-with: 10GigE setup from Aggelos Economopoulos <aoiko at cc.ece.ntua.gr>
