Description of problem:
The autoinstall process doesn't exit cleanly after a successful installation. Instead it hangs until terminated via ctrl-c. 


Version-Release number of selected component (if applicable):
ER3

How reproducible:
Always

Steps to Reproduce:
1.Run the soa GUI or console installer and create an auto-installation xml.
2.Run the soa auto-installer using the xml.

Actual results:
The installation completes succesfully but the process doesn't terminate, and the console simply hangs.


Expected results:
The process should terminate cleanly after a successful installation (ie. the command line should be appear after the "Automated Installation Done" message)

Additional info:
Appears to occur only when post-install jobs are run. If we skip all post-install jobs by ommitting them from the auto-install xml, the autoinstaller won't hang at completion.
