"vzctl stop" is taking too much time when called from a setuid binary [message #3352]

Hi!

I wrote a simple setuid binary to be able to call "vzctl stop" as a non-root user.
After compiling the binary and making it setuid it takes about 5 minutes for it to run the simple command "vzctl stop VSID". It completes successfully, but only after this delay.
Running the same command from a root shell or with sudo takes less then 10 seconds.

I attached the source of the small program.
If you run it as root it completes at normal time.
If you run it as an other user it takes a few minutes
(at least on my system, which got only 3 vps-es).

Any ideas what may cause this wait?
