What if the class extends Thread, and multiple instances run the same
function?  Would the problems outlined in the previous message still apply? 
For example:

class c(Thread):

 def __init__(self):
   a = 1
   Thread.__init__(self)

 def run(self):
   print self.f()

 def f (self):
   c.a = 2
   c.a = c.a + 1
   return c.a


myc1 = c()
myc2 = c()
myc1.start()
myc2.start()

Would the execution order outlined in the previous posting:


 A: c.a = 2
 A: c.a = c.a + 1
 B: c.a = 2
 A: return c.a (returns 2)
 B: c.a = c.a + 1
 B: return c.a (returns 3)


Still have the same results?  Or would each instance have its own set of
local variables for all functions?
