 Most of the importers slurp entire files into memory and store the results
 of parsing into memory, making for a big footprint.  They also use lots of
 unnecessary regular expressions.  Importers should parse files one line at
 a time and write posts to the DB as they are processed to help keep us
 within memory limits.
