Unfortunately, no. It really does suck up that much RAM. The compilation 
process hasn't really been a focus for the Android team.

Let me tell you, having that much filesystem cache is fantastic.  I 
dislike IDEs (especially Eclipse, and doubly so Eclipse with the Android 
ADT plugin).  But to work without an IDE you're going to be doing a lot 
of grep operations.  With my box that has 16GB of RAM, I can grep across 
250k LOC in a fraction of a second.  The same operation on my box with 
4G RAM takes anywhere from 30 sec to minutes (depending on if I have 
firefox and/or eclipse open).

I have another box that has 4G, and when running proguard on the 
aforementioned 250k LOC android app, it basically eats up all memory to 
the point where I can't run anything else on that machine if I don't 
want it to thrash.

I'm not saying that the Android build process /has/ to be this memory 
intensive, I'm just saying that it certainly /is/ that way currently. 
And given the availability of cheap RAM, it seems they have not much 
incentive to optimize that...
