Description

When resizing a terminal window running cqlsh COPY, the Python program aborts immediately with:

<stdin>:1:(4, 'Interrupted system call')

This is very annoying, as COPY commands usually run for a long time, and e.g re-attaching to a screen session with a different terminal size aborts the command. This bug affects versions 2.1, 2.2, 3.0, 3.x, and trunk.
