You have a typo in your code 
You have persisent_term not persistent_term on the last line.

About this
reading the :persistent_term documentation they say
When a persistent term is updated or deleted, a global garbage collection pass is run to scan all processes for the deleted term, and to copy it into each process that still uses it.
scan all processes: does it mean all the processes running in the VM, or just the processes that previously were using the delete/updated term?
if I have 100,000 processes and just few of them are dealing with persistent term?

As the docs said, all processes needs to be scanned to see which of them have a reference to the PT. There is no list of processes which have a reference, as the reference from the process might have been collected already via a regular GC, or the process might have sent copies of the reference to another process.
Keeping track of this would add additional complexity.

Cowboy’s documentation is also mentioned about simple usage of persistent_term.
