Message-ID: <20130606060622.GS3712@tailwind>

Summary:

+ I am writing an R extension that needs to call dmvnorm more than 
10,000 times during a model fitting computation.

+ My extension uses openmp for parallel execution.

+ As of R 3.0, it is no longer permitted for threads to call the R 
interpreter because there is a stack overflow check that always trips 
because the thread's stack is different from what R is expecting.

+ Therefore, I need a C version of dmvnorm.

+ The mvtnorm package maintainer is not interested in 
R_RegisterCCallable.

Can a C version of dmvnorm get added to the R core?
