Winbindd limited by select

Good point about non-smbd processes being winbindd clients.  I've got
some myself :-)

Also agreed about benefits of shutting down idle connections -- just not
done yet.

But if you are having a system hard limit of 1024 FDs per process, for
example, which you can't raise via setrlimit, you could only configure
less than that number of smbds.

Coupling these numbers does not make sense IMHO for another reason:
Every process can become a winbind client, even without knowing about
winbind or Samba, via NSS and PAM. How to take these into account?

I think winbindd shutting down idle connections (not immediately, there
may further requests come along quickly, and never if a connection
carries a getpwent/getgrent status) is less trouble.
