I'm creating multiple zip files with lots of calls to zip_add(). Is there a way to prevent the next one from being called until the current one has completed? It's spawning up to four simultaneous processes, which I'd like to prevent.

Nope, not possible.

There's something oddly comforting in hearing such an absolute answer from you, Don.

Well, it won't really solve the problem but you could use the wait scripting command between each zip_add and hopefully the previous one finish before the next on starts.
