[erlang-questions] Memory allocator

I noticed in Ulf Wiger's presentation Erlang Programming for Multicore:

http://ulf.wiger.net/weblog/2009/01/23/erlang-programming-for-multicore/

...that the main contention point in R13A is now the memory allocator.

Are there any plans for addressing this, such as moving to a different
memory allocator, maybe:

tcmalloc: http://goog-perftools.sourceforge.net/doc/tcmalloc.html
hoard: http://www.hoard.org

I'm curious how much something like this would improve Erlang's
performance.  Perhaps I'll try benchmarking Erlang with these allocators
versus plain vanilla libc.
