Iterating through all the features of a large SDF file causes a
significant loss of the system available memory. This is due to the
system disk cache which tend to use all the memory it can get.
The fix is to remove the random access option when opening the SDF file.
That reduced the memory used by the disk cache to a reasonable amount
and did not impact the performance of the SDF provider(it actually
helped a bit).
