Hi Mathias,

This patch removes checking of socket descriptor value in daemons.
It was checked to be less than FD_SETSIZE(1024 usually) but it's not
correct.
To be exact, the maximum value of descriptor comes from
rlimit(RLIMIT_NOFILE).
Following kernel code determines the value :
get_unused_fd_flags()
