[Gdal-dev] Potential thrashing on band 1?

[Ben Discoe]

Thanks Frank.  In case anyone else sees the thrash message, i made it go
away by increasing the cache with GDALSetCacheMax().  In this case, default
cache size was 10MB but my row of tiles was 12MB.

Curiously, gdalinfo reports a block of size 4093x21.
