To test libseccomp, check out my superh branch from here:

> https://github.com/glaubitz/libseccomp/tree/superh

then build and test with:

# ./autogen.sh && ./configure && make && make check && make check-build && cd tests && ./regression -T live

Maybe Michael Karcher has any idea what's wrong with the strace stuff?
