+ Exploit knowledge of APR pool allocation interna to allocate sightly
+ larger capacity stringbuf containers without actually using more memory.
+ Justification:
+   Very low computational overhead that should prevent costly
+   re-allocations when working with small or empty strings.
+   Also, this does not make the functionality (correctness) 
+   of the code depend on APR internals.
