I just pushed a modbv example,
   https://bitbucket.org/cfelton/examples/src
if anyone is interested.

I also took the opportunity to measure the execution speed CPython vs 
PYPY with this example.  Again it was about an 8x improvement, updated 
table below.

+---------+----------+----------+
|         | CPython  | PYPY     |
+---------+==========+==========+
| USBP    | 4m.50s   | 2m.28s   |
+---------+----------+----------+
| LED     | 16m.13s  | 1m.59s   |
+---------+----------+----------+
| RWA     | 178m.89s | 21m.71s  |
+---------+----------+----------+

System configurations
Ubu  - AMD Athlon LE1620 1.7GiB RAM, Ubuntu (natty)


Question, has anyone ran a performance test with a design that has many 
generators?  The examples I have run so far are all small number of 
generators.
