Well the idea (and the way it works on .net) is to spin for a short while and
then to resort to kernel waiting operations. From MSDN: "ManualResetEventSlim
uses busy spinning for a short time while it waits for the event to become
signaled. When wait times are short, spinning can be much less expensive than
waiting by using wait handles. **However, if the event does not become signaled
within a certain period of time, ManualResetEventSlim resorts to a regular
event handle wait.**" (emphasis mine)
