As a result of the latter PEP, +the shutdown procedure of CPython has also been changed to be more heavily +reliant on the cyclic garbage collector, significantly reducing the +number of modules that will experience the "module globals set to None" +behaviour that is used to deliberate break cycles and attempt to releases +more external resources cleanly. + +Furthermore, I am heavily involved in the current round of updates to the +Python packaging ecosystem (as both the lead author of PEP 426 and +BDFL-delegate for several other PEPs), leaving little to spare to work on +this proposal. The other developers I would trust to lead this effort are +also working on other things. + +So, due to those practical resource constraints, the proximity of Python +3.4 deadlines, and recognition that making too many significant changes to +the low level CPython infrastructure in one release is likely to be unwise, +further work on this PEP has been deferred to the Python 3.5 development +cycle. + + Proposal ========
