I also create manual areas.list files.  My experience is that even if  
I set max-nodes smaller in splitter, it can still create tiles that  
are too big for mkgmap.  My rule of thumb is that no tile created by  
splitter should be bigger than ~20MB (compressed, obviously).  This  
makes it easy to spot tiles that are too big and I've not (yet) had  
mgkmap fail when applying this rule.
