It makes perfect sense this way and I've risen the limit to 64M without problems that makes me very sure about this limit and mmap :). Maybe this behaviour could be documented somewhere and the apc.php could tell about which mode is being used instead of telling: "Shared Memory 1 Segment(s) with 64.0 MBytes" which would make me think that its actually using one shm-segment of 64MB instead of mmap with a given size.
