Still trying to write shorter posts. Did better this time. Most here probably know this stuff but it’s still good to write things like this down.

Good post. One thing I noted is that
persistent_termcopy on write is the least problem of writing. Rewriting or deleting an entry inpersistent_termtriggers global garbage collection (global as in “in every process”). Since the data is not copied on read, processes store pointers to this data directly, not in their heap, but in this persistent_term storage. So when you change the entry, each process needs to copy the old value from the persistent term into their heap and replace the pointer to the heap one.adamu
My experience reading this was:
Beginning: haha cute, this is aimed at newbies.
End: oh, really? I need to do more reading.
