I confirmed that "%08x" % int(y) works. And yes, I'm hoping so.
It actually works that way if the v is less than or equal to 0x7ffffffff.
Please try the test script. It's essentially the same test with
some more print statements. All but test d-3 appears to be ok.

I'm interested in your patch. What's the other half still missing?

And here is the result

3 7fffffff
----test b----
1 Hey! I'm waken up!

2 Hey! I'm waken up!

7fffffff
----test c----

3 80000000
----test d----
1 Hey! I'm waken up!
<type 'long'>
2 Hey! I'm waken up!
80000000
3 Hey! I'm waken up!
