compile time just like he did with other entries that use `usleep(3)`. The
alternate version and the original version were swapped in the `To build`, `To

The backlog was changed to 10 and this solves the problem. It is not known if
this was specific to macOS but it was not specific to a browser as Safari and
Firefox both had the problem.
