Objects don't literally live in threads. Objects live in an address space. This is exactly like finalization of unreachable objects in managed environments. If a thread holds some objects which are only accessible to it, when that thraed terminates, they become garbage. They necessarily get reclaimed by a different thread, and that one will run their finalization hooks, if any. If an object is used by only one thread during its lifetime, that means that it doesn't require locking. However, the thread which reclaims the object does not run at the same time as the thread which died, so there is no race between the two. That aspect of it is fine. The destructor cannot make the assumption that it is executed by that same thread. E.g. if the object contained a stashed copy of the thread ID of the original thread, the destructor would be wrong to assume that the the thread which is executing it corresponds to that ID. -- TXR Programming Language: http://nongnu.org/txr Cygnal: Cygwin Native Application Library: http://kylheku.com/cygnal Mastodon: @Kazinator@mstdn.ca NOTE: If you use Google Groups, I don't see you, unless you're whitelisted.
