Feature or enhancement

Proposal:

The SyncManager provides support for various data structures such as dict, list, and queue, but oddly, it does not support set. This inconsistency feels little bit weird.

Unless there is a specific reason, I propose adding support for set as well.

from multiprocessing import managers

managers.SyncManager.set()
set.add('foo')
# ... something else ...

Has this already been discussed elsewhere?

The SyncManager provided support for various data structures such as dict, list, and queue, but oddly, not set.
This introduces support for set by defining SetProxy and registering it with SyncManager.
