David Carlier	e6c2fd44fc	DragonFly support fix (for 5.8.x and forward). ... The pthread slot approach is somewhat buggy (pretty visible with the stress unit test which segfault more or less randomly, but the stats never show up). Using the default approach instead, the test passes eventough it s relatively slow (e.g 1.5 sec on FreeBSD vs 4.5 on DragonFly with same machine).	2020-10-22 11:15:37 +01:00
