@waltdisgrace Adding a mainloop timer here is definitely the way to go. If you haven't looked at the mainloop stuff before (especially glib's implementation and what we've built on top of it), this could be a little bit confusing. The basic idea is that we fake being multithreaded by looping over a queue of events that can come from various sources like file or network IO, UNIX signals, periodic or one-off timers, and so forth. Using the main loop allows us to avoid blocking other work from happening.

Basically what you want to do here is remove the sleep call and all the code after it up to the return. Instead, add a timer that gets triggered in one second and calls a callback that does the same stuff as what you removed.

Testing is probably best done with a ctslab run.
