[dmd-concurrency] draft 6

[Andrei Alexandrescu]

I'm done with basic messaging and entering the shared qualifier. I've 
reshuffled a fair amount of text, so you can expect new/improved 
material starting around section 4.5, "Exchanging Messages Between Threads".

I'm looking for a good example of a class for explaining shared and 
synchronized. Right now I use Date, but I'm hoping for something more 
challenging that contains an indirection. Any ideas, please let me know. 
Thanks!
