This should be easy to do. You can get the current Thread object like this:
import threading
t = threading.currentThread()
Then you can get and set arbitrary attributes on that thread to achieve
thread-local storage. So a simple implementation of a function that gets a
thread-local connection could look like this:
import threading
def getConnection():
t = threading.currentThread()
try:
return t.thread_local_connection
except AttributeError:
connection = CreateConnection()
t.thread_local_connection = connection
return connection
