FYI I merged a reduce-allocations branch to next for testing. It came from 
Milian here:
 
 https://github.com/steveire/CMake/pull/1

Milian also mentioned the possibility of using something like a sqlite 
database (probably what you meant by out-of-core above) for definitions for 
querying by the daemon. 

I also mentioned some possibile optimization possibilities, such as removing 
the closure of definitions created for all directories. I wrote a branch 
which does that some months ago, but it resulted in a slow down. I'll see if 
I can rebase the commit to master and push it to github, together with a 
patch for avoiding computing the hash multiple times in cmDefinitions. 

Thanks,

Steve.
