>Description:
after update XFree86 to 4.2,
the enlightenment must be "exec enlightenment" alone in ~/.xinitrc

~/.xinitrc Example:
*CASE 1:
  xterm &
  exec enlightenment
*RESULE: hang

*CASE 2:
  enlightenment &
  exec xterm
*RESULT: start up ok!

*CASE 3:
  exec enlightenment
*RESULT: start up ok!


The Other problem also happened , the enlightenment cannot restart!


>How-To-Repeat:
intstall newest /usr/src /usr/ports and XFree86-4 and enlightenment
use enlightenment as window manager.

but try run some xterm before it in .xinitrc
>Fix:
the enlightenment hangs in wait4() system call

HERE are ktrace & kdump results
