Sure.  Given enough effort all programming problems are solvable.  The
question is what is the effort, and what is the benefit?

At the moment to me it looks like the effort is not insignificant and I
don't see the benefit.  However, that may well just mean I haven't
thought of something.  Can you give a quick outline of how the cleanup /
error handling might work, and what advantages using named semaphores
