No time now (pymalloc is a non-starter for 2.1).  Was tried in the past on
Windows.  Helped significantly.  Unclear how much was simply due to
exploiting the global interpreter lock, though.  "Windows" is also a
multiheaded beast (e.g., NT has very different memory performance
characteristics than 95).
