Scott, correct me if I'm wrong, but does Natty still have the hard limit of 1024 files open per process? If so, should be ask people to go vote for https://bugs.launchpad.net/ubuntu/+source/linux/+bug/663090 ?
Getting that limit raised might avoid increasing numbers of support requests from users who can't figure out why Wine can't run their p2p downloader ( http://bugs.winehq.org/show_bug.cgi?id=25015 ).
So it turns out it's not a kernel config issue per se:

The initial hard limit value is not a CONFIG option, so the only way it can be changed is by carrying a patch in the kernel, something I would prefer not to do. This is the macro that initializes the hard limit:
include/linux/fs.h:#define INR_OPEN 1024 /* Initial setting for nfile rlimits */
What is the issue with having upstart set this limit early in the boot cycle? Won't all new processes inherit the modified limit?
If that's a good idea then we need to retarget the bug
