T1002123 spell checker

I thought this would be a five minute fix but it turned out to be more difficult. At least I could remove my first AspectJ code.
The mono reconciler sets 500ms as default delay, therefore this line doesn't change anything. But I think it is good documentation (we don't need to lookup the sources of the mono reconciler to find out what delay is configured) and we are safe against changes in the mono reconciler (unlikely but who knows).
