Matthew Dillon 327f4e8394 Limit number of simultanious asynchronous swap pager I/Os that can 
be in progress at any given moment.

    Add two swap tuneables to sysctl:

	vm.swap_async_max: 4
	vm.swap_cluster_max: 16

    Recommended values are a cluster size of 8 or 16 pages.  async_max is
    about right for 1-4 swap devices.  Reduce to 2 if swap is eating too much
    bandwidth, or even 1 if swap is both eating too much bandwidth and sitting
    on a slow network (10BaseT).

    The defaults work well across a broad range of configurations and should
    normally be left alone.
