Resend, slapd daemon.c error

[Robert Rothlisberger <rwroth@netdox.com>]

Resend I missed some things,

 Hello again,

	I tracked down this error (below)
	Basically when one thread is in the process of doing the
	unbind, the main thread sees activity on the fd.  So I
	added the following code to daemon.c . 

	Although the error probably does not cause any real damage.
	I prefer to not see any, since it makes it eaiser when tracking
	down real problems.

	Questions
	1) Can I assume that c[i].c_ops[0].o_tag be unbind? Are all
operations
		removed from the list until the last one left is the
unbind?

	2) Should the writewaiter be blocked also?
