----------------
* increased sleep value in statistics creation loop from 10 to 500 microseconds. This
reduces accuracy of statistics values somewhere after the decimal points but saves
CPU time.
* avoid additional sync() calls when writing partial shape data (attribute name data)
to disk. sync() will still be called when the shape marker (will be written after
the attributes) is written to disk
