I can already in principle make the current GenBank parser
up to four times faster - I was working on this before all the
FASTQ stuff and would hope to see this in Biopython 1.52,
http://bugzilla.open-bio.org/show_bug.cgi?id=2738

Even with a change like that to speed up feature location
parsing, it would still be faster still to skip the features in
a GenBank or EMBL file completely.
