Thanks for the suggestions - sounds like a couple good options, I
apprecieate it.

I have a thread that is off reading things some of which will get

The reader-thread and the UI-thread will both want to write stuff to
the same output file. What first comes to mind is that there may be
write collisions, ie both trying to write at the same time.
Should I do something like:
if busyFlag:
while busyFlag:
sleep(10)
else:
busyFlag = True
{write stuff to file}
busyFlag = False
in both threads? Is there some other approach that would be more
appropriate?
Thanks in advance for your advice
If you're using the threading module, I suggest you look at the
threading.RLock class:
my_lock = threading.RLock()
...
with my_lock:
{write stuff to file}
or, if you're using an older version of Python:
my_lock = threading.RLock()
...
my_lock.acquire()
{write stuff to file}
my_lock.release()
