Omnitask 

(variant of "multitask")

To simultaneously perform all aspects of a given job. Usually used in reference to a fast-paced workplace when an employee is abandoned by all of his or her co-workers and forced to get the entire job done alone.

For example, an employee working at a fast food restaurant all alone must juggle taking an order, performing the cash transaction, making the food, dressing the food, packaging the food, and filling drinks all at the same time to minimize the total time taken to complete the order - when each of these different tasks is normally assigned to a separate person.

At night, I run this entire place myself. I don't just multitask, I have to omnitask.

To multitask on more than one operating system at one time.

It was hard to pay attention to the conversation when I was omnitasking by listening to music and word processing on the Mac, whilst chatting and image manipulating on Windows on the PC.

To go beyond multitasking, to do basically the maximum of things at the same time.
Not necessarily only for IT systems; can be across any group of task.

"Man, I am overloaded! I am reading this manual, typing emails, listening to conference calls and telling my dog to stop chewing my slippers, while my mates are texting with me."
"You are omnitasking!"
