I don't understand.  If it doesn't make it through the first time,
why would increasing the NUM_ROUNDS make a difference?  The problem
seems to be that the formatting function fails with ENOMEM when it
tries to fill out a format of "%011000d\n", period.  That should
take up approximately 11,000 bytes -- well below 10MB.  It returned
ENOMEM on the first try.
