I just finished my testing and checked in the changes into the 1.2 tree. 
1.3 will come later, I have to finish first the test compile.

I didn't not add any intelligence to use he '-s' flag only on low memory 
systems, since the performance impact is much less then I initially thought.
The archives are so small, that it doesn't take much longer to unpack 
them. We still can add this if we have to, but I would suggest to wait 
and see.
Biggest impact was the removal of the clamav virus signatures and the 
squidguard blacklists.

DL can now boot again with only 20 MB of RAM !
I'm sure we could bring it down to 16, but that's not the goal of DL. So 
the official minimum will be 32 MB.
