Installed a test VM with current Debian Jessie amd64.
With attached small test program I could observe the 90 seconds delay
while having v208 installed (test program blocks in signal handling,
basically the same what happens to kdesud, probably because of
kDebug/kWarning usage in signal handler).
However, after installing v215 (apt-get install systemd/unstable) I
was not able to see the delays at all.
Therefore I think this bug can be closed, sorry for the noise.
Kind regards,
Bernhard
