No, they're written to every time you enter the lsp_quant_* routines
below. The only reason why this isn't catastrophic is that even wrong
values (two threads writing at the same time) will only produce slightly
sub-optimal results. The fix I proposed was to make the variable local
in each function, since the value is never used after the function
