After rereading http://bugs.python.org/issue9778 , I'm growing concerned about an impending ABI freeze before the core devs find time to fix the 32-bit hash limitation. ISTM, the use of 64-bit builds is growing in popularity.  It was be a bummer to have a locked-in an effective size limit for dictionaries and sets because the API only supports 32-bit hash values. The thread seems to show agreement that the hash values should be Pyssizet but the chance to fix it will be lost unless core devs get more time to work on the problem or unless the ABI freeze is deferred.

I think the panic is a bit of an overreaction. PEP 384 has still not been accepted, and I haven't seen a final decision about freezing the ABI in 3.2.
