Correct? Does "a file" mean a particular file with 11 or fewer lines?
It certainly doesn't work in generality for larger files:

C:\junk>cat iter_titter.py
fsim = ["Line " + str(x) for x in range(20)]
count = 0
iterator = iter(fsim)
for line in iterator:
     if count > 10: break
     print line
     count = count + 1
for line in iterator:
     print line

C:\junk>python iter_titter.py
Line 0
Line 1
Line 2
Line 3
Line 4
Line 5
Line 6
Line 7
Line 8
Line 9
Line 10
Line 12
Line 13
Line 14
Line 15
Line 16
Line 17
Line 18
Line 19

Looks like a bit of a whoopsie with Line 11.
