Why should that be: "off course"? The random module you spoke about
was also only thread unsafe if you called the same random generator
from various threads. Using a randon generator per thread shouldn't
have been a problem. Since you mentioned that, I thought that was
the kind of thread safety you were after.

I can't give a guarantee, but there are no global statements and there
doesn't seem to be assignments to cross module variables I think it
would be a safe bet.
