[Rd] Goto memory alignment query...

Several days back, I posted a comment/question from Kazushige Goto (the
developer and maintainer of Goto BLAS) -
"By the way, please ask your R developer to rewrite memory allocation
function including garbage collection. They give 4 byte offset memory
region and never perform well (or it will cause segmentation fault. 4
byte offset is fatal). Since R use complex double precision, memory
alignment should be at least 16 bytes..."
Goto obviously has thought an awful lot about such things, and
(apparently) wrt to R (and he is extremely well-known in programming
circles - you don't write a BLAS unless you know a thing or two). Since
a number of R users (like me) make use of Goto BLAS, I'd hope that on
the devel group could comment/reply. I'll forward to Goto.
