[racket-dev] Passing flvectors to BLAS and LAPACK

How hard would it be to allow flvectors to be passed to foreign 
functions as double pointers?

BLAS and LAPACK linear algebra functions primarily accept pointers to 
floating-point arrays in row-major order. If we could send flvectors 
directly (or at least pointers to their elements), we could reuse the 
`FlArray' type for LAPACK-accelerated matrices, cut down on copying, and 
more easily transparently use LAPACK on systems that have it.

Would it require somehow allocating flvectors with 'atomic-interior so 
they wouldn't be relocated?
