[Python] How to read lines from a mmapped file?

Is seems that the mmap interface only supports readline(). If I try to iterate over the object I get character instead of complete lines.

What would be the "pythonic" method of reading a mmap'ed file line by line?

import sys
import mmap
import os


if (len(sys.argv) > 1):
STAT_FILE=sys.argv[1]
print STAT_FILE
else:
print "Need to know <statistics file name path>"
sys.exit(1)


with open(STAT_FILE, "r") as f:
map = mmap.mmap(f.fileno(), 0, prot=mmap.PROT_READ)
for line in map:
print line # RETURNS single characters instead of whole line
