[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.
