Ask me about "spooning", yes, I'm that old.
I've not heard of unspooning though.
Spooling is the process of a sending data to a spool, or temporary storage area in the computer's memory. This data may contain files or processes. Like a spool of thread, the data can build up within the spool as multiple files or jobs are sent to it. However, unlike a spool of thread, the first jobs sent to the spool are the first ones to be processed
Interesting.
