Cell disruption without sonication

I like to resuspend the cells in Tris + protease inhibitor (PMSF) and 
treat with lysozyme for about 20 minutes.  Then add Triton X-100 to 0.5% 
and MgCl2 to 5 mM.  The Triton gives nice lysis, while the MgCl2 helps tie 
up (or aid in the digestion of) the DNA, providing a nice solid pellet 
(say, 20-30 minutes at 3000xg).
