New submission from Aaron Meurer <asmeurer at gmail.com>:

(The corresponding SymPy issue is https://code.google.com/p/sympy/issues/detail?

The SymPy test suite (i.e., clone http://github.com/sympy/sympy and run `bin/test` 
with PyPy) uses way too much memory with PyPy. On my Mac, the virtual memory goes 
up to several GB before the tests are finished, according to Activity Monitory. On 
an old Linux laptop with no memory, the tests barely start before they exit with 

I cut the tests short after about 1GB was used according to Activity Monitor 
(right after the core tests were finished), and ran a gc dump on the process. The 
result is at https://gist.github.com/asmeurer/5359631.
