Strange problems in APC 3.1.3p1 (from package php-apc):
apc.slam_defense and apc.write_lock ini settings seem to have no effect at all - I keep getting [apc warning] potential cache slam averted ... error messages doing these things:
1) apc_add('foo', 'bar'); apc_store('foo', 'baz'); - although documentation says that apc_store won't raise warning if key exists.
2)apc_add('foo', 'bar'); apc_delete('foo'); apc_add('foo', 'baz'); - gives the same error, and it seems like apc stores every key and apc_delete just rewrites the value to false.
