    This is on amd64, 2 dual-core Opteron CPUs with 16GB of RAM, running
    2.0.2_STABLE. This is the first time we've really exercised all the memory
    (mostly using mmap to move large files in/out of memory).

    It's not immediately obvious how to increase the size of the PV pool; it appears
    that pmap_alloc_pv() should be doing this dynamically as needed, and I guess
    it's failing.

    Can someone help? We pushed this system pretty hard with 8GB and didn't have
    this panic (we got a different one, 'uvm_mapent_alloc: out of static map
    entries', which I seem to have managed to configure away...)

    Thanks. This is ... kind of important.
