How to Destroy Defunct Process

I have E-17 with bling module enabled. They seems to work perfect, but recently become unstable. Fortunately I have ttyN to switch and kill. But, it seems they always become defuncts.

You cannot kill already dead process. It seems they become restless souls wandering... (Spooky..) :P
But, you could let them go to heaven by killing their parent.

# pstree
or
# ps afx

find any defunct process (don't forget to see their process id) and then kill all the process that not defunct.

# kill -9 141411
or
# killall -9 enlightenment

In my case, wait for few minutes/hours, then it would be cleaned up.
