DemiMarie:

PyPy has poor performance on workloads with a large number of unbiased branches, due to poor inter-trace optimizations.

Hyperblock scheduling solves this problem by merging several traces into a single combined trace.  See [LuaJIT's issue 37](https://github.com/LuaJIT/LuaJIT/issues/37) for more information.
