This can be considered good or bad depending on design philosophy / idiosyncrasy. Unix programmers consider the ability to pass pieces of data in fast and reliable manner between processes without any special userspace-visible locks or synchronization to be an advantage of this model.

This is why X clients talk to X server over one file descriptor with already multiplexed events, and can add other file descriptors to their loops when necessary.
