Issue Description

i configured nsslapd-enable-nunc-stans in dse.ldif and started dirsrv. I verified that the setting is set with:

$ ldapsearch -D 'cn=Directory Manager' -y p -h localhost -b 'cn=config' | grep nsslapd-enable-nunc-stans
nsslapd-enable-nunc-stans: on

I would expect:

strace -fF -s 1024 -p $(pidof ns-slapd)

To show epoll syscalls but instead i am still seeing select syscalls.

ldd /usr/lib64/dirsrv/libnunc-stans.so.0
        linux-vdso.so.1 (0x00007fffa99fa000)
        libevent-2.1.so.6 => /usr/lib64/libevent-2.1.so.6 (0x00007efc603f1000)

small update: when putting queries onto the 389-ds it starts using epoll. what is the select loop for then?

From IRC conversation:

richm: what is the select thread used for?
either waiting for output ready on a single fd, or instead of sleep()
richm: aha
