Shared variable in Python Process subclass

I was wondering if it would be possible to create some sort of static set in a Python Process subclass to keep track the types processes that are currently running asynchronously.

class showError(Process):
    # Define some form of shared set that is shared by all Processes
    displayed_errors = set()

    def __init__(self, file_name, error_type):
        super(showError, self).__init__()
        self.error_type = error_type

    def run(self):
        if error_type not in set:
            displayed_errors.add(error_type)
            message = 'Please try again. ' + str(self.error_type)
            winsound.MessageBeep(-1)
            result = win32api.MessageBox(0, message, 'Error', 0x00001000)

            if result == 0:
                displayed_errors.discard(error_type)

That way, when I create/start multiple showError processes with the same error_type, subsequent error windows will not be created.
