[Sami Halabi]

Hi,
I opened 2 terminals with user sody.
in first i hit "su -", and supplied password, it was stcuked.
in the other I did:

%ps xau | grep su
sody  39830  0.0  0.0  9124  1500   0  S+    4:51PM   0:00.00 grep su
root  39812  0.0  0.0 21732  2088   1  I     4:49PM   0:00.00 su -
root  39813  0.0  0.0 21732  2108   1  I+    4:49PM   0:00.00 su -
%procstat -kk 39812
  PID    TID COMM             TDNAME           KSTACK
%procstat -kk 39813
  PID    TID COMM             TDNAME           KSTACK
