WARNING! WARNING! DANGER WILL ROBINSON! DANGER!

This is a SERIOUS design flaw. Do not do this. Use rsa keys. Unless you
don't care about security. But you are using ssh so I assume you do.

Well popen is no more insecure then storing a cleartext password to feed
to ssh above. So I dont see what the problem is in that area.

Im sure someone will tell you exactly how to manipulate a running process.
But PLEASE use rsa keys for ssh and not passwords.
