The old fashioned way was to have a 'deleted' flag in the CSV file, instead
of removing a line simply set the deleted flag, i.e. one field, when you
parse the CSV file look for the deleted flag, if set the line is 'deleted'
so ignore it.
Once in a while go through the CSV file and physically remove all rows
flagged as deleted, if your CSV file is getting too big.
Now the next problem is what if 2 people are writing to the file at the
'same time'?
