Emulator: linux_base-fc-4_10 and friends from package.

browser: linux-firefox-2.0.0.12 from package.
	others version of linux binaries from mozilla.org.

>Description:
I have some aliases like:
-------
% alias 
m1     su - user1 -c "export DISPLAY=:0; firefox &"
m2     su - user2 -c "export DISPLAY=:0; firefox &"
% 
-------

to use web browser as a diffrent uer. If I issue "m[12]" to run a
second firefox, but I get a ``new window'' from running firefox which
runs under diffrent user account.

some notes:
 - linux-seamonkey has same behavior.
 - conjunction w/ freebsd binary and linux binary of firefox have same
   behavior.
 - FreeBSD/amd64 7.0-REL has same behavior.
 - 7.0-STABLE (upto "src-7.0216") kernel with 7.0-REL world has same
   problem.

 - ``su user[12]'' on diffrent xterms, then run firefox w/o problems
 - linux-mozilla-1.7.13_2 (from package) has no problems

BTW, I can do ``echo "export DISPLAY=:0; mozilla &" | su - user1'' on 
a FreeBSD 4.11-STABLE system.
