In the hack there I have assumed that signals make a copy of slots before executing them and hence that hack would work -> it would delete the actual functor when connecting dummy() and then the copy once slot() returns (assuming that the signal had been fired and the control was inside slot() when stop() was called). Is that assumption correct (about copying the list of slots before executing them) ? I got it from: http://stackoverflow.com/a/4490785/1060004
It avoids copying the slot list unless it has to (it has to when you connect a slot while an invocation is in progress). If it does have to copy the slot list, it will clean up all the disconnected slots from the new copy and discard the old copy when all invocations using it complete. These are implementation details though, it would be best not to rely on them.
