I finally got around to setting up a FreeBSD (release 11.0) virtual machine.
It too has the same behaviour as Linux, in that the shared memory key gets
changed to 0 (i.e. IPC_PRIVATE) when shmctl with IP_RMID is applied. So I
expect most other OS's follow this behaviour.
Hence I think it would be better to revert the commit
22c3fafb25b742973d7122edc626b30d03bdb36c, rather than apply this patch.
And thus accept one needs to externally control the memory segment should the
memory size change.
Side note - I couldn't find anything in the Debian packaging - as I expected
it would attempt to use the ipcrm command when gpsd is uninstalled/upgraded.
