Here are my answers please take them with a grain of ignorance.

I do not think prefilling the dictionary will do much good since 
LZ is all about finding prefixs anyway.

I am for copying the sourcecode into our source-tree we don't 
want to be dependent on LZ4 library being available on the users 
system.
I think re-implementing it in D is also fine as long as the 
function is extern(C).
However I agree with Martins point: It is a waste of resources 
re-implementing something that already has a perfectly fine 
implementation.

The only reason why I re-implemented the LZ4 decompression was to 
use it at CTFE.
