I use slapd on Linux 2.1.130 with glibc, without threads and with tcp wrapper
support compiled into slapd.  A refused connection leads to the following
debug output:

listening for connections on 3, activity on: 5r
before select active_threads 0
select failed errno 9 (Bad file descriptor)
[...repeating]

I had the same problem with the current stable release and I am willing to
test experimental patches or provide more details.
