s recommended that you inspect
    the actual kernel source code (see the function
    <CODE
CLASS="FUNCTION"
>vm_enough_memory</CODE
> in the file <TT
CLASS="FILENAME"
>mm/mmap.c</TT
>)
    to verify what is supported in your kernel before you try this in a 2.4
    installation.  The presence of the <TT
CLASS="FILENAME"
>overcommit-accounting</TT
>
    documentation file should <SPAN
CLASS="emphasis"
><I
CLASS="EMPHASIS"
>not</I
></SPAN
> be taken as evidence that the
    feature is there.  If in any doubt
