GNU Parallel Bug Reports recstart finds spurious empty records

[Martin Frith]

Hello,

I'm using GNU parallel 20120822, and I tested it like this:

##################
echo ">" > junk.fasta

seq 10000000 >> junk.fasta

cat junk.fasta junk.fasta > junks.fasta

parallel --pipe --recstart ">" wc -c < junks.fasta
##################

There are only 2 records, but it finds lots of extra records of size zero.

Related to this, parallel seems to become slow when the records are much bigger than the block size.

I hope this is useful information,
have a nice day,
Martin Frith
