Robert, thanks for your reply.
I read the rest of the document, but please take in account that my
question wasn't about "avoiding".
My question is "in which cases"?
I repeat my question. Tuplesort.c and logtape.c DO implement tapes on
disk and currently they do not request 2x or 4x of the input space: so,
again, in which case implementing tapes on disks requires between 2x and
4x of input space?
Thanks for your attention.
Manolo.
