Well, thanks for all the advice, but the really simple solution is called AGI.
All it took was a few lines of Perl script, without any classes, to solve this issue.
I have rewritten the script, so that it can be used to call any linux command or script, while having music or a message playing in the background. I also added an option, to force the listener to hear the full message if you would like.
To use this script, just create a file in the /var/lib/asterisk/agi-bin/ directory, called system_background_agi.pl
Copy the attached code to it, and save.
Change the file mode to 755
Now in your asterisk Dial Plan, add something like this one line of code
exten => s,n,agi(system_background_agi.pl|'LinuxCommand CommandOptions'|MusicFileName|1)
The last '1' is optional, and it will force listeners to hear the whole message. Otherwise message stops as soon as LinuxCommand returns.
I hope this helps amyone out there.

$system_response = `$ARGV[0]`;

$response = ; #force previous Stream File to finish
