Bug #8969: Puppet hangs trying to replace a FIFO
https://projects.puppetlabs.com/issues/8969

Branch:
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:
<pre>
mkfifo /tmp/boom
puppet apply <<EOT
file { "/tmp/boom": ensure => file, content => "Hello, World" }
EOT
</pre>
