Frank,
IPython is great, but it is not a replacement for a shell like bash. If
you have a Linux
matically keep the use cases
up-to-date.

Three to four months before `strange errors`? I'd spend some time
correlating logs; not just for your program, but for everything running
on the server. Then I'd expect to cut my losses and arrange to safely
re-start the program every TWO months.
(I'd arrange the re-start after collecting logs but before their
analysis.
Life is too short).

Google for YAML and JSON formats too.

The folowing will make the data available for garbage collection no
matter what references it:
>>> l = ["data"] *10
>>> l
['data', 'data', 'data', 'data', 'data', 'data', 'data', 'data',
'data', 'data']
>>> l2 = l
>>> l[:] = []
>>> l2
[]

But to give them credit though, in Whats new in Python 2.5: PEP 308,
they do mention that as a matter of style you should parenthesise the
if-expression, and the example given consistes of just a simple
assignment of the if-expr to a name.

Yep, definitely a case of overdoing the list comprehensions when you
throw away the list.
I'll watch out for that in the future,

With respect, (hehe), maybe you need to indicate that you've searched
the Python documentation on __name__ and __main__?
