I've noticed the same both in terms of the dependencies now being drawn in and 
in terms of how much RAM the compile consumes.  On systems with low RAM I set 
lower MAKEOPTS jobs and average values and add plenty of swap.  This keeps 
emerge in check and stops it from swapping in and out continuously thrashing 
the disk.

More than a year ago I'd noticed similar uncontrolled consumption of resources 
by emerge on Chromium.  Interestingly a few versions later something must have 
changed (some hardware limit checks added by devs?) and Chromium became much 
less hungry for resources.
