in secop.proxy the callers modules method announceUpdate is
called from an other thread while the accessLock is locked,
creating a deadlock. solve this by creating an other lock
'updateLock' for the update.
+ add status parameter even to non-Readable proxy modules,
in order to indicate a failed connection
+ fix an error in secop_psi/softcal.py
