"removeObject:" should be "removeObserver:" in [-TSocketServer dealloc]?

in lib/cocoa/src/server/TSocketServer.m
---------------------------------------- this may be wrong

• (void) dealloc {
  [[NSNotificationCenter defaultCenter] removeObject:self];

---------------------------------------- this may be correct

• (void) dealloc {
  [[NSNotificationCenter defaultCenter] removeObserver:self];

----------------------------------------

isn't it?
