All large systems eventually run into scalability problems. SCons handles
dependencies as accurately as possible, and sometimes those dependencies do
not scale linearly, but this is a problem of all systems.

The stub-wrapper is still in the works, but the memory optimizations have
been completed and are available in the latest distribution.
Once the stub-process wrapper is complete, I think all the planned
performance improvements will be complete.

Python 3 support is still incomplete, but there is an effort to make the
current baseline Python 3 compatible.
