Hi,
this is result for changing mainline to dataflow branch on memory
tester.
Looks like there are issues.
http://www.suse.de/~gcctest/memory/results/200703240516/
are results for dataflow
http://www.suse.de/~gcctest/memory/results/200703211153/
are results for mainline
I will switch tester back to track mainline later today.
