I tried playing around with the flags in the tox.ini file. There are 
options to run this in multiple processes. There are two flags that are 
of interest:

1. NOSE_PROCESS_RESTARTWORKER: - This is documented as follows:
"--process-restartworker
                         If set, will restart each worker process once their
                         tests are done, this helps control memory leaks 
from
                         killing the system. [NOSE_PROCESS_RESTARTWORKER]"
2. NOSE_PROCESSES: - This is documented as follows:
"--processes=NUM       Spread test run among this many processes. Set a
                         number equal to the number of processors or 
cores in
                         your machine for best results. [NOSE_PROCESSES]"

The problem that I have is that when the first variable is set nothing 
is done, this is really dependent on the second. The problem when 
setting the second is that I get the following exception:

Has anyone ever encountered something like this.
Thanks
