I'm good. :)

I tried this, but I got a bunch of errors. Basically, what I tried
precisely are:

struct pooled_vectorS { }; // the selector

namespace boost {
  template <typename ValueType>
  struct container_gen<pooled_vectorS, ValueType> {
    typedef std::vector<ValueType, pool_allocator<ValueType> > type;
  };
};

Unfortunately, when I try to do:

typedef adjacency_list<
  pooled_vectorS,
  pooled_vectorS,
  undirectedS,
  property<vector_name_t, int,
    property<vector_distance_t, int,
      property<vector_color_t, int>
      >
    >
  > graph_type;

graph_type my_graph;

I get a whole slew of errors which all boils down to:

/usr/local/lib/boost/boost/graph/adjacency_list.hpp:282: error: no
type named 'type' in 'struct
boost::parallel_edge_traits<pooled_vectorS>'

Am I missing something here?

I'm using the version in r41409.
