Any questions?  I'm looking at bobandgeorge.com in firebird; compiling a 
new kernel; running Gnome2 with a set of applets. . . xscreensavers . . . 
it's cool.  The registration system works and everything.

A quick hack is there now (not in my running copy) to NOT load LZO if 
it's not my default alg.  I'm shakey on its stability.  WKdm is fine.

I can't see how meta data goes to swap.  Castro, you'll have to rewrite 
the swap meta data stuff.  Use a meta_data structure (there's one in 
comp_cache.h) and sizeof() and stuff this time!  I don't want to have to 
massively hack through the code to change the meta data that goes to 
swap!
