  As suggested, I checked out the swap and memory space on my system.  My 
setup is a 700MHz cpu, 128Mb of ram and equal swap space.  The 'free' command 
shows, that there are approximately 100Mb in use, and an equal amount of swap 
space unused.

  I built the kernel in the following manner....

  Untar the linux 2.4.3 kernel tree... enter that directory.
  zcat <path>/linux-2.4.3-core.patch.gz | patch -p1
  zcat <path>/linux-xfs-patch.gz | patch -p1
  make xconfig
  {
    enabled entities are: athlon, ne2k network card, parallel port, usb,
    busmouse,nfs v3, server v3,automount,ppp async/sync,i2c,video,
    ntfs (read only),udf,ufs,reiser fs,xfs,advanced partitions,xfs partition,
    sound,acl support
  } 
  make dep
  make bzImage
  { put the arch/i386/boot/bzImage into the /boot and edit lilo etc :-) }
  cp System.map /boot/System.map-<kernel> and symlink.
  reboot. into the new kernel.

  side note on compile: GCC that comes with RedHat 7.1, does not work
                                 for compiling the XFS kernel, as it will
                                 break on compiling the XFS code for anything
                                 except i386.  The setup also uses kgcc to
                                 compile the kernel, which is provided with
                                 compat-egcs, which compiles the kernel ok.

  Other kernel modules are added, such as Alsa and Nvidia, but I don't think 
they effect this.  The same thing as above, was done for the redhat 2.4.2-2 
kernel.  But that time, the xfs core file for that RH kernel was used, along 
with the linux-xfs patch, to alter the kernel.  This kernel behaves the same 
way as the vanilla 2.4.3 one.

  This time, I'm using the 1.0.1 tree of XFS on kernel 2.4.5 (vanilla), and 
without ACL compiled into the kernel.  It works well, no problems and the 
kernel is far more stable than the 1.0 one.  No hangups yet, whatsoever.  But 
the differences in sizes of the filesystem after the data has been untarred 
onto it, persists.  But the sizes are not constant this time, rather vary 
each time I do it.  After I unmount and remount the drive, the size is fixed 
to normal (well, a little larger than ext2fs, but that is due to difference 
in block sizes,etc).
