I solved that problem by introducing a module "depository" that has my
"global" stuff that I want shared between threads. It is full of lines like
"hash_table={}" and so forth. Then in my modules I just

import depository

and down further, to access my "global" hash_table,

names=depository.hash_table.keys()   # get list of keys in hash table for
expire purposes

and voila. 

Yes, it works across threads. Just make sure to properly use semaphors if you
are doing operations on multiple structures (e.g., if I had two tables
"hash_table" and "hash_table_weights" and needed to keep them in sync). You
may wish to create some helper functions in your depository module to handle
the locking/setting/retrieving of such structures.
