I want to retry locking a file for a number of times and then give up,
in pseudo-code it would be something like:-
for N times
try to lock file
if successful break out of for loop
if we don't have a lock then give up and exit
How does one do this tidily in python?
for i in range(N):
if try_to_lock_file():
break
else:
raise RuntimeError, "Could not lock file"
do_real_work()
Note the indentation of the `else` clause, it belongs to the `for` loop
and is executed only when the iteration is completely exhausted.
