In issue #1866 an issue was reported under docker, by which a user cannot lower the number of FD needed. It looks like a restriction imposed in this environment, but it results in an error while it ought not have to in the case of shrinking. This patch adds a new function raise_rlim_nofile() that takes the desired new setting, compares it to the current one, and only calls setrlimit() if one of the values in the new setting is larger than the older one. As such it will continue to emit warnings and errors in case of failure to raise the limit but will never shrink it. This patch is only preliminary to another one, but will have to be backported where relevant (likely only 2.6).
