I have created a collection of patches to the R 2.13.0 source that

the patches I posted in September 2010, though often with additional
improvements. Other patches are new.
The patches, along with detailed documentation, are available from
For some discussion of these patches and their benefits, see my blog
I believe that these improvements to the R implementation should be of
substantial benefit to the R community. The R core team is welcome to
incorporate them into versions of R that they release in the future.
