I found this one on the train (look at SyntaxError_init, it's
obvious).  I also found a number of other bugs in the new exceptions.c
code, from leaks:

>>> def f():
...     try: UnicodeEncodeError()
...     except TypeError: pass
... 
>>> for i in range(10):
...     f()
...     print sys.gettotalrefcount()
...

30826
30831
30836
30841
30846
30851
30856
30861

to potential crashes:

>>> s = SystemExit(); s.code = []; s.__init__(); s.code
[[...]]
Bus error

So I think I'll be reading through exceptions.c pretty carefully.  I
don't think Sean and Richard have acquired as much paranoid
anal-mindedness and I have when hacking on Python C internals yet :)

Cheers,
