Thanks, here are the revised numbers. The end result of massive paging is, obviously, unchanged. ;-)
The delta between RPRIV and RSIZE appears to be .25 GB for my situation.
Xcode is using roughly 6.75GB of RPRVT, the 8 Clang instances are essentially the same (I guess not much memory overhead in the shared frameworks for Clang).
So: I'm seeing thrashing after a good 3/4ths day of work, with Xcode pigging out to 6.7+ GB of real private memory, which is causing the 8 1-1.5GB Clang instances to start paging with 16 GB of RAM.
