Both the soft and hard limits for all the rlimits really need looking at.
In most cases the hard limits are much too high!

I'd have thought the soft thread limit should be relatively low (maybe
more than 160), and the hard limit say 1024 (dunno really).

Similarly for fds, maybe 256 and 4096.
At the moment there are nice local-user DoS because of the hard limit
values.
