[R] Compiling R with multi-threaded BLAS math libraries - why not actually ?

Hello all,
I came across<
http://www.r-bloggers.com/performance-benefits-of-linking-r-to-multithreaded-math-libraries/> David
Smith's new post
Performance benefits of linking R to multithreaded math libraries<http://blog.revolutionanalytics.com/2010/06/performance-benefits-of-multithreaded-r.html> Which explains how (and why) REvolution distribution of R uses different BLAS math libraries for R, so to allow multi-threaded mathematical computation. What the post doesn't explain is why it is that native R distribution doesn't use the multi-threaded version of the libraries. Is it because R-devel team didn't get to it yet or is it for some technical reason. Could someone please help to explain the situation?

Thanks in advance,
Tal

p.s: I wasn't sure if to send the question here or to R-devel, I decided to send it here. If I am in the wrong - please let me know.
