Ticket 50905 - intermittent SSL hang with rhds
Bug Description:
On a successfull sasl bind, a new IO layer (sasl_io_enable) is registered on top of
the connection. Then sasl bind sends the successful result. Registration is
done while sasl bind thread holds c_mutex but result is sent while the c_mutex
is released.
If a new operation comes in just after c_mutex was released it is
possible that sasl bind sends the result while the new IO layer is pushed.
IO layers is partially initialized at that time. It can create sigseg or
deadlock or...
Fix Description:
The fix is to protect the send result from IO layer push.
i.e. move send_ldap_result into c_mutex
