	Hmm ... I found it happened also for simple
	echo-server/echo-	client in $ORBIT_PREFIX_DIR/test
	
	may i show you some  commands and the result ..on my box .


	bash# pwd
        /root/ORBit-mt-0.5.7/test
        bash# ./echo-server > echo.ior &
        [1] 8868
	
	bash# ps ax | grep server
	 8868 pts/5    S      0:00 lt-echo-server
 	 8883 pts/5    S      0:00 grep server
	
	(then i execute echo-client ...)

	bash# ./echo-client `cat echo.ior `
	time elapsed:0.011061 seconds.
	bash#

	now  i doing "top" in other window while echo-server still running
	.the result of top below ..


  PID USER     PRI  NI  SIZE  RSS SHARE STAT  LIB %CPU %MEM   TIME COMMAND
 8868 root      18   0  1144 1144   940 R       0 99.4  0.4   2:32 lt-echo-server
  786 root       9   0 36756  35M  1984 R       0  0.1 14.4   0:06 X


	Did something wrong ...
	can You see lt-echo-server still has "R" state,even  client has
	exited ..


	Here what i got with sample in $ORBIT_PREFIX_DIR/multithread

	

bash# pwd
/root/ORBit-mt-0.5.7/test/multithread
bash# ./server > cal.ior &
[2] 8934

bash# ps ax | grep server    
 8868 pts/5    R     16:00 lt-echo-server
 8934 pts/5    S      0:00 lt-server
 8952 pts/5    S      0:00 lt-server
 8953 pts/5    S      0:00 lt-server
bash# ./client `cat cal.ior `
now calculating 880 x 506 for 4 seconds.
now calculating 309 x 280 for 9 seconds.

(till exited)

in another window of top show this ..


PID USER     PRI  NI  SIZE  RSS SHARE STAT  LIB %CPU %MEM   TIME COMMAND
8868 root      16   0  1144 1144   940 R       0 49.3  0.4  18:03 lt-echo-server
