I run the test again. I run git clone --reference, git checkgout
origin/dccp as usual. It does not show 2.6.27-rc8 in the DCCP tree,
only 2.6.27. Is that correct?
# `uname -a`

I compiled dccp as module, disabled CONFIG_SECURITY, CONFIG_USBNET and
Ipv6 as per Gerrit suggestion and CONFIG_MODULES=y as per Arnaldo
suggestion. Here it is the strace result:
`strace -f -e trace=network iperf -sd`
