  First thing I notice is that you pass one byte at a time. At best
this is just massively inefficient, at worse you're hitting a bug .
The source from parse4.c does not do this.
  Also if you have converted to a memory string, why do you need to use
progressive parsing ? If the conversion is progressive, I still doubt
it delivers data byte by byte, just pass the blocks as they are converted.
