But you know what? I'm not angry, because I've come out stronger in the end. Check this out; the new and (against all odds)
improved World Load Detector for Terraria 1.4.X:
The most obvious upgrade is that it uses an entirely new settle detector which requires not an endless flow of water, but one single solitary block's worth of water for each load cycle. This water is supplied by a new integer-rounding-powered water duplicator based on jRNGn's design
here. It no longer needs to evaporate water as part of its operation, so you can stick it wherever you please. It's nearly the same size as the previous design (one block wider and one block shorter), so old worlds using 1.3.X WLDs won't need extensive remodeling. And the best part is that it only barely registers as "bug-abusing" on a technicality, meaning that unless Re-Logic expressly goes out of their way to screw with me, this design is going to be immune to any surprises that the last few hotfix updates might spring on us.
Plus, y'know... quarter second timers are kinda nice.
