Which variants of the netstat command are causing the problem? You can
run ssh-rand-helper -vvv on its own and watch its progress.

If there are processes hanging around after ssh-rand-helper times them
out it means they're ignoring a SIGINT, so either it's being
deliberately caught or (more likely) the command is stuck in a syscall.

The best long-term solution is to use prngd instead of the built-in
entropy gatherer.

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
