Log:
OLPC XO-1.5 - strobe HDD_LED# during fs-update.  The LED is toggled once for each zblock: line in the input file.  This shows the processing speed, and is affected initially by complexity of decompression, and eventually by SD card write rate.  Faster and slower SD cards are more easily compared.  Cost of 1.7 microseconds per LED toggle, but as writes to SD are asynchronous the run time is unchanged.
