I was on the Goto BLAS maillist yesterday, asking some question about 
relative speed/performance/tuning of Goto BLAS and (specifically) R.

I received a reply from Kazushige Goto (the developer and maintainer of 
Goto BLAS), who as part of his answer to some of my queries made the 
following comment concerning R, which I pass along to the R development 

"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..."

Apparently, Goto has run into some issues with R before.  I'll assume 
that some out there will be able to interpret Goto's comment/suggestion.
