 The issue occurs when a 3rd party application is editing the SHP file.
 Note the spatial index IDX file is FDO specific and it will not be
 updated. Thus it is getting stale.

 A solution is checking the timestamps of the SHP and IDX files. If the SHP
 file has been edited since the last IDX file change, that would indicate a
 3rd party edit to that SHP file. It is a valid solution to this problem
 since the IDX create/recreate/update is based on reading the current SHP
 records. Thus the timestamps will reflect the sequence of operations.

 The C++ function to get the filestamp is stat() which can retrieve the
 last modified date. It is available both on Windows and Linux.
