Do you hold a mutex locked while invoking a callback?
What mechanism do you use to suspend till it's time to fire a callback?
What is the precision of your library? I mean if you instruct the 
library to invoke your callback in so many ms usually your callback will 
be invoked at bit later. The question is how long later? Or earlier?
Does the precision degrade when you register lots of callbacks?
What's the smallest possible timeout the library lets to register a 
callback with? How does the library handle small (e.g. 1 ms) timeout 
requests?
What platforms does the library work on?
