We've had several cases today, where people came swooping in and deleted 
nodes from an ongoing upload, where the ways hadn't been uploaded yet. 
Okay, it happens, wish JOSM would sort the upload on object locality[1]. 
In this case it was just a mapper that didn't know what that 'field of 
nodes' was all about.

Then there was another, where someone came in about 40 minutes after a 
botched upload, while the uploader was still trying to repair this and 
attempting to reuse those nodes where possible, and started his script 
to 'helpfully' delete those 'duplicated nodes'. I just wish those 
scripts would only process nodes that have been idle for a few days, and 
not very fresh ones.
