I've got the POSIX.4 spec here and I'm reading it (well, the bits about
shared memory, since I'd like W to have that ASAP even if I don't do it
:-)...  SysV shared memory is _similar_ to POSIX shared memory.

I'm going to have a go at implementing it so it can be added to
MiNTlibs, but I don't think some things are going to be possible, or
will need to be faked (like memory-mapping a file... has anyone got any
brilliant ideas on how to implement that on a system with no MMU?).

If I find I'm too lazy to implement it, I'll post a summary to the MiNT
list so someone else can get started.  :)
