multiple gksudo's at the same time isn't nice

[Eric Feliksik]

Problem: `gksudo ls & gksudo ls & gksudo` makes my X very inresponsive, 
looks like hanging...
I kill gksudo in tty1, problem solved. Weird command of course, but... 
double/triple clicking the update-notifier applet causes a similar 
situation.

Is it for security that when gksudo is started, it's the only accessible 
think in X? Nice! But maybe gksudo should prevent this interfering with 
itself?

Should I file a bug for gksudo?
