Amaury reported that when the following warning is reported by haproxy: [WARNING] (296347) : config: failed to get shm stats file slot for 'haproxy.stats', all slots are occupied haproxy would segfault right after during clock update operation. The reason for the warning being emitted is not the object of this commit (all shm-stats-file slots occupied by simultaneous co-processes) but since it was is intended that haproxy is able to keep working despite that warning (ignoring the use of shm-stats-file), we should fix the crash. The crash is caused by the fact that we detach from the shared memory while the global_now_ns and global_now_ms clock pointers still point to the shared memory. Instead we should revert to using our local clock instead before detaching from the map. It should be backported in 3.3
