- The Boehm-Demers-Weiser conservative garbage collector can be used as a
- garbage collecting replacement for C malloc or C++ new. It allows you to
- allocate memory basically as you normally would, without explicitly 
- deallocating memory that is no longer useful. The collector automatically 
- recycles memory when it determines that it can no longer be otherwise 
- accessed."
