sync did not flush the buffers..also the file cache is at about 
136 megs.  Under top it is labled as 136587k cached that is what 
i am looking to clear out.  Also how do i turn the swap back on?
I am doing this as the various echo commands have still not 
completly fixed the kernel swapping bug..:(

My "Foundation" verse:
Isa 54:17  No weapon that is formed against thee shall prosper; 
and every tongue that shall rise against thee in judgment thou 
shalt condemn. This is the heritage of the servants of the LORD, 
and their righteousness is of me, saith the LORD.
