Description:
        [Detailed description of the problem, suggestion, or complaint.]

usually i run BASH in xterm, as non-root user. When i need root privileges, i
use "su root" command, and after that, i use the "suspend" command to retrieve
non-root privileges.

Having used "suspend" by mistake without doing "su root", my bash was completly
freezed.

        to occur.]

bash in xterm uid != 0

% tty
/dev/ttyp0
% id
uid=1003 .......
% su root
Password:
# id
uid=0(root) ......
# suspend
% id
uid=1003 .......
% suspend (HERE IS THE MISTAKE, RESULTING TO A BASH FREEZE)
