Rudder

Even in the most simple case (a directive not used anywhere, on a fresh Rudder install), deleting a directive takes several seconds.

Code hint: the cause is that along the deleting, we get the directive from LDAP (with a lock), then get the the active directive (with a lock for the same think), then need to wait until the exaustion algo of the locking system sort things out. This is, of course. BAD BAD BAD BAD.
