it's a bit tough sometimes.  the reason is that, by default, a process will
hang when opening a named pipe unless there is a process on the other end.
this is by design and one has to use non-blocking io to avoid it, eg

   f = open 'named.pipe', File::RDWR|File::NONBLOCK

something to be aware of...  here's an example of some code which uses named
pipes between a c program and ruby
