<blush> Thanks, it's very gratifying to know the patch had a positive
impact.  You're seeing even more of an improvement that I did on
Gerald's testcase.  That's great.  I'm interested to see reports from
other very large (c++) packages.

The same code is also in 3.4, so you should see similar improvements
there.

BTW, (I may have missed it) what's your OS, how much memory does your
system have and does physmem.c report it accurately?
