I don't see an easy way to write a test for it.

But if you have a close look at the
"s4:ldap_server: add call->wait_send/recv infrastructure" commit:
https://git.samba.org/?p=metze/samba/wip.git;a=commitdiff;h=6172e59eba6be35a8cdc3dc436ca166f1aeeefaa

You'll see that ldapsrv_call_read_next() (and also
ldapsrv_call_writev_start()) is deferred until the
waiting is over, which means we won't detect a connection drop
until we write or read from the socket.

So the outside behavior of the connection is still the same,
it's blocked during a bind call. The difference is that
other connections are no longer also blocked.
