# Description
Sometimes changing file descriptor limits is not allowed, but there is
no need to crash the node if/when this happens. Since `fdlimit`'s author
decided to use panics instead of returning `Result`, we need to catch
it.
# Checklist
- [x] My PR includes a detailed description as outlined in the
"Description" section above
- [ ] My PR follows the [labeling requirements](CONTRIBUTING.md#Process)
of this project (at minimum one label for `T`

See #1345, <https://github.com/paritytech/substrate/pull/14207>.
This adds all the necessary mixnet components, and puts them together in
the "kitchen-sink" node/runtime. The components added are:
- A pallet (`frame/mixnet`). This is responsible for determining the
current mixnet session and phase, and the mixnodes to use in each
session. It provides a function that validators can call to register a
mixnode for the next session. The logic of this pallet is very similar
to that of the `im-online` pallet.
- A service (`client/mixnet`). This implements the core mixnet logic,
building on the `mixnet` crate. The service communicates with other
nodes using notifications sent over the "mixnet" protocol.
- An RPC interface. This currently only supports sending transactions
over the mixnet.

* Print "stalled" task on shutdown
When the node is shutting down, we give the Tokio runtime 60 seconds to shutdown. If after these 60
seconds there are still running tasks, we now print these tasks. This should help debugging nodes
that have stalled tasks.
This pr introduces a `TaskRegistry` that keeps track of all running tasks. Each task registers and
unregisters itself in this `TaskRegistry`.
* Fix rustdoc
* Update client/service/src/lib.rs
* Ensure that we inform all tasks to stop before starting the 60 seconds shutdown
The change of waiting in maximum 60 seconds for the node to shutdown actually introduced a bug. We
were actually waiting always 60 seconds as we didn't informed our tasks to shutdown. The solution to
this problem is to drop the task manager as this will then inform all tasks to end. It also adds
tests to ensure that the behaviors work as expected. (This should already have been done in the
first pr! :()
