    run out of KVM through a mmap()/fork() bomb that allocates hundreds
    of thousands of vm_map_entry structures.

    Add panic to make null-pointer dereference crash a little more verbose.

    Add a new sysctl, vm.max_proc_mmap, which specifies the maximum number
    of mmap()'d spaces (discrete vm_map_entry's in the process).  The value
    defaults to around 9000 for a 128MB machine.  The test is scaled for the
    number of processes sharing a vmspace (aka linux threads).  Setting
    the value to 0 disables the feature.
