The IPC is in SystemV flavor but I think these days we normally should adopt Posix IPC instead especially for Linux/BSD, am I missing something?
"On Linux and FreeBSD there is big advantage of posix queues, as handler given by mq_open are basically file descriptor which can be polled/epolled/selected/kqueued"
"all POSIX IPC is thread-safe, while most SysV IPC is NOT"
