Something in the code introduced to improve the discovery process has managed to produce a failure where the main operations block for too long, causing the zombie watcher to attempt to restart, but it's unable to kill the main process.

Have to figure out a reliable way to force the killing... also need to figure out a way to avoid these hard-deadlocks. Sigh. I've already done 10 (unbillable) hours on this today. That's so not good.

I'm ready for bed right now, but that means leaving the scanner running in a state that may freeze again overnight (not ideal). Still, not thinking coherently enough to trust any changes I make just now, so I suppose I'll just go to bed and risk having it go nuts (won't hurt anything, will just stop doing it's job).
