	And that is fine it really is to document the fact for the source reader and to catch the hypothetical case that the default interval will be increased in the future...

	Well, the powers that be need to decide, I believe the comment is helpful enough to having made it, but insignificant enough to not warrant its dedicated line or block of lines. First let’s see whether the comment survives in its verbosity and then care for style. That said, I am happy to keep monitoring this and potentially make the change.

	Oh, even better, I just see you fixed it for me; thanks a lot (sure beats having to clean up after myself ;) )

	At least to me that sounds like a decent strategy, no?

	Since I only have commit permissions at tc-adv (I am not asking for more) I will just play with the tc-adv repository and hope Jonathan will cherry pick (or even just implement the ideas in his own way) everything he considers worth it…
