10174	MythZoneminder - Mapped memory - Patch	Argus <pthorn-mythd@…>	paulh	"Mythzmserver doesn't support ''memory mapped'' Zoneminder installations, which have become the default in recent releases (1.24.4). For instance, after an upgrade to Ubuntu Oneiric, the zoneminder apt package is compiled with mmap support by default, which no longer interoperates with mythzmserver out of the box.

As a workaround, the Mythzoneminder wiki entry is clear about this and suggests the recompile and installation of Zoneminder from source using shared memory options, which should work fine.

Instead, I'd like to suggest the attached patch to make mythzmserver compatible with the memory mapping method, while maintaining the original shmget() functionality as a failover.

Tested using branch fixes/0.24 and Zoneminder 1.24.4 (Ubuntu repository packages).
