Solve the following python programming problem given the following code:
@ deferredAsThread 
def findProcesses(self) : 
    "Attempt to find a process by an ASSIMILATION pattern.
           This is a relatively naive attempt to find an application
           that works in most cases. 

           NOTE:
             If your ASSIMILATION pattern includes group matches the 
             dictionary will be updated with the output of
             ``groupdict() from re.search``.  If droned is able to
             read the environment settings from the application that
             will be inlcuded in the result dictionary as well.
