  Log:
  SVN rev 193260 on 2009-06-01 20:35:53Z by jhb
  
  Add a simple API to manage scatter/gather lists of phyiscal addresses.
  Each list describes a logical memory object that is backed by one or more
  physical address ranges.  To minimize locking, the sglist objects
  themselves are immutable once they are shared.
  
  These objects may be used in the future to facilitate I/O requests using
  physically-addressed buffers.  For the immediate future I plan to use them
  to implement a new type of VM object and pager.
