Subject:	Re: [Boston.pm] transposing rows and columns in a CSV file

This problem of transposing a matrix bigger than you want to consider slurping 
feels familiar. The techniques used to sort "big" files in the bad old days, 
disk or tape based sort-merge, might be adaptble. The trick is to do it in 2 
(or small * log N) passes,by creating a simpler suitable intermediate form.
