Here's a better version:

---
my_pages = {}
i = 0
while len(my_pages) < 4  and i < 100:
    i += 1
    rnd_page = context.other_script()
    if not my_pages.has_key(rnd_page):
        my_pages[rnd_page] = 1
return my_pages.keys()
---

This eliminates the risk of huge loop problems caused by several
predicable problems and is better style besides.

HTH,
