OS X's own timed closing feature works ... too good. That is, the keychain is closed even if I poll an imap account every 5min while the keychain is set to be closed after 10min in inactivity.

Yes, I've been looking at kwalletd's source, and more or less decided I wasn't very interested in changing them. I did get the integration with kwalletd up and running in kwallet_mac.cpp by copying over the relevant code from kwallet.cpp (or so I think), but it's as if there is no communication through the dBus.

>From what I understand, wallet management is actually asynchronous, at least as far as closing is concerned. That's not how my current version of kwallet_mac works. Is there anything (policy, API considerations, ...) against implementing a timer in kwallet_mac.cpp so that at least the idle timeout feature works from inside KDE?

Also, while kwalletmanager can open and close wallets just fine, the wallet's icons don't change state, at least not when closing the wallet. Does it wait for a (dBus) signal for that, and how can I check if at least my code does the required things to emit that signal? (Regardless of whether dBus functions correctly, I mean)

The modifications to the AuthServices make it possible to edit the kwallet configuration in the associated control module. And last but not least, password prompts no longer get posted somewhere in the background.
