That is a possibility, but for now, we do not want to support them as standard
BSD APIs.  It's probably worth noting that not very many things use them at
the moment in Linux, and I wouldn't be surprised if they are deprecated all
together in favour of procfs, here an excert from the Linux man page:

NOTES
       The IPC_INFO, SHM_STAT and SHM_INFO operations are used by the  ipcs(8)
       program  to  provide information on allocated resources.  In the future
       these may modified or moved to a /proc file system interface.

So I am really not sure how much value there would be.
