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..
