yum_package_updates fact hangs if yum is locked

[jbagleyjr]

The yum_package_updates fact hangs if yum is locked. Debug output from puppet facts shows:

Debug: Facter: State : Sleeping, pid: 16573
Debug: Facter: Another app is currently holding the yum lock; waiting for it to exit...
Debug: Facter: The other application is: yum

And the puppet run never gets passed the Loading Facts stage.

In my opinion this fact should be optional. It's a nice to have but it is slowing down my puppet runs
