Very good,

In my opinion it should be required for everyone who wants to 
participate in D's GC to read that book. So everyone has at least a 
basic understanding of the problem at Hand.

But if you read the book I don't understand, why you simply declare the 
hardest problem, percise pointer discovery, as done. To be able to 
actually implement and test a GC that is not a reimplementation of what 
we already have one needs percise pointer discovery of _all_ pointers, 
write barriers and GC halting points. So please enlighten me why you 
simply decalre this done?

Kind Regards
