                (ANONYMOUS_ZEROFILL): Rename from this...
                (ANONYMOUS_NO_CLEAR): ... to this, inverting logic.  Update 
users.
                (ANONYMOUS_DISCARDABLE): Don't define.
                (ANONYMOUS_NO_ALLOC): Define.
                (ANONYMOUS_NO_RECURSIVE): Likewise.

                (struct anonymous_pager): Add fields allocated_region,

                fill's type to anonymous_pager_fill_t.
                (anonymous_pager_alloc): Take additional parameters, P and
                ADDR_OUT.  Change the fill function's type to
                anonymous_pager_fill_t.  Require that the address is not already
                allocated.  Update users.
                * anonymous.c: Include <string.h> and <hurd/rm.h>.

offset.
                (addr_compare): Remove function.
                (offset_compare): New function.
                (storage_desc): Change node key from the addr field to the 
offset
                field.
                (fault): Rewrite to handle a fill function, discarded pages, and
                the ANONYMOUS_NO_RECURSIVE and ANONYMOUS_NO_ALLOC flags.
                (destroy): Free the allocated region and any staging area.
                (anonymous_pager_alloc): Rewrite to allocate virtual memory.  
Set
                up the data structure appropriately if ANONYMOUS_THREAD_SAFE is
                given.
                * pager.h (PAGER_REGION_LENGTH): New define.
                (pager_fault_t): Change ABI such that the callback must release
                PAGER->LOCK.
                * pager.c (pager_fault): Don't release PAGER->LOCK.
