Generally I'm not happy about the sleeps in the code, the main problem
is that the test still may fail in a case that something was slower than
usuall and we decided to proceed after we slept for a pre-defined
interval. Ideally these should be replaced with a active waiting, i.e.
loop that checks some condition 10 times in a second or so. Hoewever I'm
okay with getting this in so that we manage to have these tests in
before the release and fixing it later on.
