This is on systemd 208, Linux 3.12.1. Upon resuming from suspend, "systemctl suspend" will not exit. Instead, I have to send Ctrl-C in order to return to the shell. Might be related(?): I've recently noticed that, when invoking "systemctl suspend", the screen goes to black, then returns, and goes to black again before the system finally suspends. Originally, the screen would only go to black once. Since I have been running systemd 208 for a while, and have only recently noticed these glitches, I suppose it could be correlated with recent kernel updates.
Most likely some job is stuck taht is pulled in as part of the suspend. Please run "systemctl list-jobs" when this hang happens in another window. What does that print?
