Do you mean "while True: ..."?

Yet another attempt (untested, uses Python 2.5 conditional expression):
from itertools import chain, repeat, dropwhile
def izip2(*iterables, **kw):
fill = kw.get('fill'))
sentinel = object()
iterables = [chain(i, repeat(sentinel)) for i in iterables]
while True:
t = [i.next() for i in iterables]
# raise StopIteration immediately if all iterators are now empty
dropwhile(lambda v: v is sentinel, t).next()
# map all sentinels to the fill value and yield resulting tuple
yield tuple([(v if v is not sentinel else fill) for v in t])
