Two questions about savepoints: Bug or feature?

Hi,

I updated the CVS a few minutes before, applied Gavin Sherry's latest 
xact patch. It worked. 

Anyway...here is what I did:
==================Case 1=================================
test=# BEGIN ;
BEGIN
test=# SAVEPOINT devrim;
SAVEPOINT
test=# SAVEPOINT devrim;
SAVEPOINT
test=# SAVEPOINT devrim;
SAVEPOINT
test=# ROLLBACK to devrim;
ROLLBACK
test=# ROLLBACK to devrim;
ROLLBACK
test=# ROLLBACK to devrim;
ROLLBACK
test=# ROLLBACK to devrim;
ROLLBACK
test=# ROLLBACK to devrim;
ROLLBACK
test=# ROLLBACK to devrim;
ROLLBACK
test=# ROLLBACK to devrim;
ROLLBACK

...and it goes on forever. Is it a feature or a bug?

Now case 2:
==================Case 2=================================
test=# BEGIN ;
BEGIN
test=# INSERT INTO a VALUES ('123');
INSERT 17231 1
test=# INSERT INTO a VALUES ('1dfsd');
INSERT 17232 1
test=# SAVEPOINT devrim;
SAVEPOINT
test=# DELETE from a WHERE x ='123';
DELETE 1
test=# SAVEPOINT devrim;
SAVEPOINT
test=# DELETE from a WHERE x ='123';
DELETE 0
test=# SAVEPOINT devrim;
SAVEPOINT
test=# DELETE from a WHERE x ='1dfsd';
DELETE 1
test=# SELECT * from a ;x
- ---
(0 rows)                                                                               
test=# ROLLBACK to devrim;
ROLLBACK
test=# SELECT * from a ;  x
- -------1dfsd
(1 row)
test=# ROLLBACK to devrim;
ROLLBACK
test=# SELECT * from a ;  x
- -------1dfsd
(1 row)

test=# COMMIT ;
COMMIT

test=# SELECT * from a ;  x
- -------1dfsd

========================================

Are these all intended behaviors? I thought we wouldn't be able to give 
more than 1 same name to savepoints in a transaction, am I right?

Regards,
