On the observation that applications often make a huge number of syscalls that may not be necessary, and which require peeling back many layers of abstraction to even understand where they come from (as in the SDL case) – Dave Jones had a fun paper a little while back with a laundry list of everyday apps in the Linux ecosystem that make syscalls that seem absolutely insane, which people rarely notice because we’re not typically aware of all the subtleties of the millions of operations that our apps perform every moment: https://www.kernel.org/doc/ols/2006/ols2006v1-pages-441-450.pdf
