+1 on this. Whenever I save files within Sublime text I get conflicts which I then need to manually delete it gets frustrating. Note that Sublime, SumatraPDF do not block files so maybe another solution would be better, for instance in User selectable time delay for syncing some frequently updating files there is a proposal to delay sync. Why not sync files/folder with X+modified where X is a user configurable number of minutes or seconds (you could set the default to 0 to replicate current behavior). You could even make it part of the per folder sync settings. I cannot speak for others, but immediacy of syncing is not something I need.
