While catching every possible case where "open file limit exceeded" is
not possible, we can at least increase the soft limit to the available
hard limit without any user effort.
Do this in Ansible top-level process, even though we probably only need
it in the MuxProcess. It seems there is no reason this could hurt
Previously we exitted without calling waitpid(), which meant the
top-level process struct rusage did not reflect the resource usage
consumed by the multiplexer processes.
Existing benchmarks are made using perf so this never created a problem,
but it could be confusing to others using the "time" command, and also
allows logging the final exit status of the process.
