Yes, last fall I tried with 11-BETA and I didn't capture as much data
(actually just the final "top" screen views).

I see that I first tried to run the emulation with 128M (since that is
the most for which I have any real hardware) and this was what that
showed:

It looks like it is still creeping along but then you notice the 100%
system time ... now I may have thought, oh why did I do that, it will
be thrashing so badly on swap, it is burning my SSD into the ground.

So I restarted again I see after and just reran the build (prior completed
work left as is to speed things along) but with 512M this time ... you
get to see the same thing I captured better this weekend with RC1.  But
I know I saw this same thing with 10.1 when it came out. ... same gimple-
match.cc file ...
