Release Notes Summary:
Puppet no longer hangs when trying to replace a fifo with a file, directory or symlink

Puppet does some stupid things trying to replace a FIFO, including opening it and trying to MD5 the content.

This allows a DoS for any managed file that can be replaced with a disconnected FIFO, at least.

To reproduce:

mkfifo /tmp/boom

puppet apply <<EOT

file { "/tmp/boom": ensure => file, content => "Hello, World" }
