I'll add support for this:
\directlua{fonts.constructors.cacheintex = false}
(only useful for generic usage)

while trying to make Taco's linebreaker code I came across some

that I found rather weird
in essense it looks as if \rpcode is not ending up in the char table
unless \lpcode for the same char is set first (and non-zero)
\pdfprotrudechars=1
%\lpcode\font 50 = 1
\rpcode\font 50 = 200

local function FMItable (name,t)

if you uncomment the lpcode line then both values show up. But
what is
puzzling me even more is that if I change the values and then
run this
directlua bit again, nothing changes (could of course be that I
should
define FMItable differently but ...
anybody any clue?
sure .. the table that you see is a cached one and if you change a
rp value after the font definition it is not reflected in there
see page 158 of luatex manual : cache field in passed tfm data tbale
keep in mind that normally one will only set the protrusion values
when a font is loaded because once a font is used they are frozen
(currently these values are em related but at some point they might
become glyph width related)
