Summary:                    utils.c:938 ast_carefulwrite: Timed out trying to
write causes corruption to astdb
Description: 
Agent addmember to local extensions causes the agent to be logged as
non-existent channels when ast_carefulwrite times out during login.

[Oct 15 10:40:07] NOTICE[29962]: utils.c:938 ast_carefulwrite: Timed out
trying to write
[Oct 15 10:40:07] NOTICE[29962]: utils.c:938 ast_carefulwrite: Timed out

Here  is an example of the corruption where the same local extension is
logged twice.  The "outgoing" agent cannot logoff unless I manually remove
from astdb.  The local agent can logoff but since the outgoing cannot calls
entering queue fail to reach agents and the local channel cannot log back
in.

Local/3345 at queuefifteen-outgoing/n (dynamic) (Invalid) has taken no calls
yet
      Local/3345 at queuefifteen-agent/n (dynamic) (Not in use) has taken 2
calls (last was

I am currently testing Asterisk 1.4.27rc1
ast_carefulwrite function on main/utils.c from pre-165796. 165796 and
current code and latest code have a different version of the function so
cannot "easily" revert the patch.

And the notices are still present in 1.4.27rc1

I deleted the astdb prior to the upgrade and have all agents logging back
into the queues.  I'll have to monitor the queues with show queues to see
how long it takes until the corruption returns.
