Indeed, but that's not likely to happen even on various flavors of Unix. All I've got in mind for now are SysV semaphores which have the useful properties of 1) easily allowing N processes to acquire the semaphore and 2) automatic undo of semaphore operations when a process exits for any reason. > I would > recommend looking at the resource-list management in PHP as a means of > registering and cleaning up these semaphores. (Check out php3_list.h, > list.c, and a module like db.c to see how these functions are used.) Good idea, I'll see if it does what we need here.
