 Switched back to ZLIB compression and got the following error:

 {{{
 WARNING: ZLIB decompression error -3: data error
 ERROR: Error uncompressing fp raster data for row 2000 of <beam.206>:
 error
        code -1
 }}}

 Could there be a lurking zlib compression bug in the code that only
 manifests during parallel invocation, or, when a very large number of rows
 are involved?

 Switching back to LZ4 for more testing...
