Oddly enough I got this posting twice but not the one from ozk :-)

Anyway, yes we discussed this on IRC however I'm still unsure
if my findings in the gluestik source is correct.  It *looks*
to me like the CIB structure is held within the GS structure
which was put into kernal memory.  Worst case senerio is my
ability to read "C" listings improved?  ;-)

Hoping Scott can clear this up.  I havn't been able to recompile
gluestik but I tried.  I get errors, it's my first attempt at
recompiling anything like that.
