thread stomp?

Give us a script that works. Ideally it should output something that
indicates what the error is.

//run over files

This is not a comment in Python.

class2 threads seems to start prior to class1 threads done; class2
results depend on class1 finish first

What are you trying to do? If all you care about is making one thread
depend on another finishing, why make two threads? Just have one
thread do one thing and then do the other.

Not every problem is a threading problem.

Why are you making main a class? It should almost certainly be a
function (defined with "def", not "class").

for i in dircache.listdir(dir):
//run over files
class1(dir).start()

You've started a bunch of threads. If you want to wait for them to
all finish, you need to call .join() on them all. You can't do that
unless you save references to your threads, like this:

threads = []
for i in dircache.listdir(dir):
new_thread = class1(dir)
new_thread.start()
threads.append(new_thread)

for thread in threads:
thread.join()

Beyond that, the code you've posted is not correct. You've left off a
required ":" in your definition of class main, and your comments are
not valid python comments. Your for loops don't make a whole lot of
sense to me either. Are they supposed to be iterating across files in
a directory? If so, why do you start up all of your threads with
"dir" instead of "i" or "j" as the parameter to your new thread?
