We need to know the system level max open fds so that we won't go above that.
Simply setting the limit to RLIM_INFINITY doesn't work on Linux 3.x (EPERM), a
patch on this went into the 2.x branch but not 3.x for some reason. Also,
getting the system level nr_open is not very straightfoward on 3.x, which is
mentioned in the comment inline.

 From sysctl(2):

        "Since Linux 2.6.24, uses of [the sysctl] system call result in
         warnings in the kernel log.   Remove  it  from  your
         programs now; use the /proc/sys interface instead."

So using /proc/sys is the correct method and not some awkward workaround.

Good to know that, in which case I can remove majority words of the inline 

Will do in v2 (and reword the changeset summary).
