Comment (by X512):

 Problem can be fixed in generic way by introducing per-team permission
 flags for each kernel object.

 Possible set of permissions for each kernel object:

 ||= Object =||= Permissions =||
 || team, thread || kill, debug, send, receive ||
 || port || read, write, close, delete ||
 || sem || acquire, release, delete ||
 || area || clone, resize, set protection, delete ||
