Re: [libvirt] [PATCH 4/4] remote: Detect 'nc' version incompatibilities

This ugly thing is a shell script to detect availability of
the -q option for 'nc': debian and suse based distros need this
flag to ensure the remote nc will exit on EOF, so it will go away
when we close the tunnel. If it doesn't go away, a useless 'nc'
process is left sitting on the remote host.
Fedora's 'nc' doesn't have this option, so we can't blindly pass -q.
More info here:
I don't really like this approach. Shouldn't it be sufficient to
just explicit SIGKILL the ssh client, rather than relying on the
exit-on-EOF behaviour of nc.
