[OSM-dev] osm2pgsql memory usage

    when you run osm2pgsql in slim mode with a large cache, then could 
it not release the cache memory once it reaches the "Sorting data and 
creating indexes" stage? It is this phase where postgresql tends to 
consume a lot of memory for index creation, and the specific settings on 
the machine I'm running it on at the moment have led to all of 
osm2pgsql's 10 GB being swapped out - which, if the memory is really 
unused, isn't a big deal but I wonder if the memory could not have been 
freed anyway?
