OverflowError: cannot convert float infinity to integer
SUMMARY
dool (and dstat as well) regularly and randomly (from about once per a few hours to once per month) dies with OverflowError while printing the values, trying to convert infinity from float to integer. It sounds like a division by zero error earlier, resulting in infinity as the float value.

OverflowError: cannot convert float infinity to integer
I get this whenever a network interface no longer exist, like powering off a virtual machine, etc.
I can confirm this issue, both on dstat and the most recent dool version from AUR:

I get this whenever a network interface no longer exist, like powering off a virtual machine, etc.
Same. I can reproduce it by removing a Wireguard network interface
Yeah, the annoying thing is: docker is widespread and stopping containers also removes interfaces, crashes dool.
Partial workaround: name the interfaces to monitor with the argument -N
dool -N eth0
Doesn't help with many interfaces meant to be summed up in a total.
This issues SHOULD be addressed now in #16. If the issue remains, please re-open this issue.
