The article pointed out legitimate drawbacks related to the intersection of fork() and other features like posix threads.

The paper mentions the benefit of posix_spawn for the fork+exec use case.

I might've seen posix_spawn while skimming a manpage or browsing a change log but this is the first time that I'd actually learned about its purpose.

The article's conclusion isn't "and therefore Linux is bad" btw.
