Summary: Debug with long array takes forever

Initial Comment:
This is a bug and a partial patch.

If I debug a program that contains a ridiculously large array (8M entries in my case), the debugger takes forever.
It happens in Mac OS X, Python 2.2, but I found the bug in is the repr module, so it is probably universal.
The thing is, that after the fix below, it still doesn't work!
Did I miss something trivial (like repr is builtin, or something like that?). Would someone with Mac OS X experience help out here, please (Jack?).

Here's the diff to make repr.repr work with large arrays:
13a14
>       self.maxarray = 5
50a52,62
>     def repr_array(self, x, level):
>         n = len(x)
>       header = "array('"+x.typecode+"', ["
>         if n == 0: return header+"])"
>         if level <= 0: return header+"...])"
>         s = ''
>         for i in range(min(n, self.maxarray)):
>             if s: s = s + ', '
>             s = s + self.repr1(x[i], level-1)
>         if n > self.maxarray: s = s + ', ...'
>         return header + s + "])"
