/**
  @file
  This service provdes functions to allocate memory in a connection local
  memory pool. The memory allocated there will be automatically freed at the
  end of the statement, don't use it for allocations that should live longer
  than that. For short living allocations this is more efficient than
  using my_malloc and friends, and automatic "garbage collection" allows not
  to think about memory leaks.

  The pool is best for small to medium objects, don't use it for large
  allocations - they are better served with my_malloc.
