Please, no. The System V IPC primitives are rather clumsy to use nand are
unintegrated with the file system. Rather, implement named pipes and some form
of mapped files (even if the size of the file to be mapped must be small
and the file can't be paged in: swap it in on a map_fd call, and flush it
to disk on close, redirecting requests for that file through read() and
write() to the in-core copy).
