This is particularly important when checking if PyTables/HDF5 maintains an internally-consistent file state between saves.
It's not that I normally end my programs with 'kill -9', it's just that I've found PyTables (recent versions, anyway) usually leaves my files in an internally-inconsistent state and I'm trying to make my application more fault tolerant. >PyTables registers a cleanup handler (it flushes and closes open files) >that runs on program exit.
