>+          <para>No, there is no memory leak, and it's not using 256 Mbytes
>+            of memory.  It simply likes to (i.e., always does) map an
>+            obscene amount of memory into its address space for convenience.
>+            There is nothing terribly wrong with this from a technical
>+            standpoint; it just throws off things like &man.top.1; and

>+            worrying about remapping it later when it needs to grow, it maps
>+            it with a generious size.  This is very evident from the source
>+            code, where one can see that the length argument to &man.mmap.2;
>+            is <literal>0x10000000</literal>, or one sixteenth of the
>+            address space on an IA32, or exactly 256MB.</para>
