With API 0,6 the edits will not be lost; the uploading editor will 
receive an error message when trying to overwrite someone else's edit 
with something based on an older version. I don't know how Potlatch 
deals with this, but in JOSM you should, at least in theory, be able to 
avoid any problems by downloading before uploading; worst case is you 
get conflicts that you have to resolve manually.
