I've fixed one bug in my modular IPC patch and updated it to 2.1.131-ac2.
The bug is a potential race between module deletion and the IPC syscalls.
If you don't want to grab -ac2, the fix is appended (it's very short).

The full patch may be found at

As before, any comments, bug reports, etc. are greatly appreciated. Thank
you to all the people who sent feedback on the last version.
