Yes, that's correct.
Suggestion for the IPC: Perhaps fifo* should be renamed to ipc.* (or
whatever) to avoid the confusion what's used.

Note there is a script: $GISBASE/dev/create_buffers.sh to be run
to get proper files if *not* using fifos. Maybe, Jeshua, you have been
missing that? Perhaps a
make clean
make
helps to be sure that everything compiles o.k.
