You.... may want to rename that function... I just had a whole box of Runts candy to myself.
That's a LSP you can put in your startup suite... of course... if it's in the startup suite, it'll only load once, when Autocad opens. ORRRRRrrrrrrrr you could have a button assigned to a macro that fires that LSP, ORRRRR what you SHOULD do to obtain the desired results, is put:
(setvar "layernotify" 0)
(setvar "layereval" 0)
In the end of your acaddoc.lsp file. That'll load it every time you open a drawing. These variables are drawing-dependent, not universal, so you can't "set it and forget it" every time Autocad opens.
