   I copied the working block below the failing block.
   The blocks are now:
   1 copied from failing
   2 working blocks
   1 original failing block
   1 working block
   This is producing 4 characters of output, from 5 identical blocks. A
   working theory is that only the original failing block is failing,
   which can be tested by removing it. An alternative theory could be that
   only the last block is failing. A tertiary theory could be that a
   different block is failing each time, or that it the unexpected output
   is unrelated to failure of a block.
   As I type this I will likely make errors from my perception issues.

   Output drops to three when the "failing" block's output line is
   removed!
   This means it is not my delusion of it being when and how the source
   bytes were written, which makes it much easier to troubleshoot.
   I'm guessing there's some code after all the blocks that quickly
   removes the character last output. Something nice and logical.
   Whew.
