I haven't used Distributed Services (DS) since the pre-1.0
days, but it used to be that the IPC key space allowed keys
in the range 0x0 - 0xffffffff .
Of those keys, the ones available to users were:
0x30000 - 0xfffff -- keys returned by create_ipc_prof(3)
0x10000000 - 0xffffffff - keys returned by ftok(3)
The rest of the keys are unavailable.
