This is needed because GNU libc headers does not allow an applications to
dynamically change the __FD_SETSIZE at compile time, and it is the base of a
number of important data types.. Why this is I don't know as there is nothing
in the library depending on __FD_SETSIZE, or in the kernel...

This makes no difference as there cannot be 8192 disk filedescriptors of 8192
in total (many will be used for networking).

If you are tuning max_open_disk_fds, then it should be set to a suitable
backoff limit. Else leave it unconfigured to not confuse people.
