What would make atlas suddenly decide to start running its tuning code

without that happening? It's frustrating since even though I am using
make -j32 the tuning code is taking forever...
I've also got an ATLAS build problem with sage-5.12: it builds on one
(virtual) machine but not on its host, even though both are running the
same operating system, OpenSuse 12.3. This also seems to be related to
tuning issues:
I see "Cannot detect CPU throttling." in the virtual machine's build
log, where all is fine.
I see this in the failed log:
It appears you have cpu throttling enabled, which makes timings
unreliable and an ATLAS install nonsensical. Aborting.
See ATLAS/INSTALL.txt for further information
Ignoring CPU throttling by user override!
There are also seemingly more serious statements, like these:
g++ -g -c cf_algorithm.cc -Wall -fno-implicit-templates -I. -I.. -I.
