While I'm not sure how much of Roy's comment was "hah, hah, just 
serious", this has been my biggest issue with long-running Python 
processes on Win32 -- either power outages the UPS can't handle, 
or (more frequently) the updates (whether Microsoft-initiated or 
by other vendors' update tools) require a reboot for every 
${EXPLETIVE}ing thing.  The similar long-running Python processes 
I have on my Linux boxes have about 0.1% of the reboots/restarts 
for non-electrical reasons (just kernel and Python updates).

As long as you're not storing an ever-increasing quantity of data 
in memory (write it out to disk storage and you should be fine), 
I've not had problems with Python-processes running for months. 
If you want belt+suspenders with that, you can take others' 
recommendations for monitoring processes and process separation 
of data-gathering vs. front-end GUI/web interface.
