610919e5e6 auth pycredentials: incorrect PyArg_ParseTupleAndKeywords call
The challenge parameter was being treated as a string rather than as a
data blob.  This was causing intermittent seg faults. Removed the
server_timestamp parameter as it's not currently used.

Unable to produce a test case to reliably replicate the failure.
However auth_log_samlogon does flap

f5f05a644d ctdb-readonly: Avoid a tight loop waiting for revoke to complete
BUG: https://bugzilla.samba.org/show_bug.cgi?id=12697

During revoking readonly delegations, if one of the nodes disappears,
then there is no point re-trying revoking readonly delegation immedately.
The database needs to be recovered before the revoke operation can
succeed.

However, if the revoke is successful, then all the write requests need
to be processed immediately before the read-only requests.  This avoids
starving write requests, in case there are read-only requests coming
from other nodes.

In deferred_call_destructor, the result of revoke is not available and
deferred calls cannot be correctly ordered.  To correctly order the
deferred calls, process them in revokechild_destructor where the result
of revoke is known.
