Im not exactly a kernel guru (and unless you mean kernel data structures)-
I must say that using SysV IPC (or any other UNIX system calls) does
require a good knowledge of how things are implemented under the hood.
System calls (depending on sw and hw issues) have a finite
capacity/latency etc. which a product developer needs to understand to
take care of race conditions, scalability etc..
