Comment(by ezyang):

 I wonder if we're hitting this:

 {{{
     /* The size argument we are given includes all the per-thread
      * overheads:
      *
      *    - The TSO structure
      *    - The STACK header
      *
      * This is so that we can use a nice round power of 2 for the
      * default stack size (e.g. 1k), and if we're allocating lots of
      * threads back-to-back they'll fit nicely in a block.  It's a bit
      * of a benchmark hack, but it doesn't do any harm.
      */
