No,
while 1:
r = self.fifodev.readline()
if r: print r
else: time.sleep(0.1)
is ok (note the "if r:" clause).

Beautiful! Thanks Martin!

yes, but you have to follow the usual file handling rules, and close/re-open
the fifo after detecting EOF. You will be blocked on attempting to re-open
until there is another writing process.

while 1:
fp = open('my_fifo', 'r')
while 1:
line = fp.readline()
if line == '':
break
print line.rstrip() # To prevent printing of \n in line
fp.close()
