When APC is compiled with mmap support (Memory Mapping), it will use only one
memory segment, unlike when APC is built with SHM (SysV Shared Memory) support
that uses multiple memory segments. MMAP does not have a maximum limit like SHM
does in <literal>/proc/sys/kernel/shmmax</literal>. In general MMAP support is
recommeded because it will reclaim the memory faster when the webserver is
restarted and all in all reduces memory allocation impact at startup.
