I noticed that if a file is being continuously written to, the file

Because it does not look, as Ian explained.
def getLines(f):

for line in f:

return lines
This nearly duplicates .readlines, except for using f an an iterator.
Try the following (untested):
with open('/var/log/syslog', 'rb') as f:
lines = f.readlines()
# do some processing with lines
# /var/log/syslog gets updated in the mean time
lines = f.readlines()
People regularly do things like this with readline, so it is possible.
If above does not work, try (untested):
def getlines(f):
lines = []
while True:
l = f.readline()
if l: lines.append(l)
else: return lines
