  So that's what's going on. But if I have to dup the blocks then 
I have the same problem as before with limited memory issues. I 
kinda wish more there was the gz_open that is in the C interface 
and let it deal with the decompression and memory management as 
appropriate.

I suppose i could incorporate a 8 byte header file that has the 
length before/after that are 0's and just drop 630Mb from the 
data that can be skipped... which is the bulk of the compressed 
data. I just hoped to keep it very simple.
