> DocumentsWriter writes the number of stored fields, up front, into the
> fdtLocal buffer.  Then, as each field is processed, it writes each
> stored field into this buffer.  When the document is done, in a
> finally clause, it flushes the buffer to the real fdt file in the
> Directory.
> The problem is, if an exception is hit, that number of stored fields
> can be too high, which corrupts the fdt file.
> The solution is to not write it up front, and instead write only the
> number of fields we actually saw.
