That's pretty annoying, eh? You can call pvmfexit() first, which is
supposed to disconnect your program from the pvmd, but then when you
call pvmfhalt() it re-enrolls you, so your process gets shut down.

The workaround I use is to simply shut down the daemon "manually" via a
shell command in my program. In Fortran that would be

CALL CSYS('echo halt | pvm > /dev/null')

Of course you should use pvmfexit() first. I don't know how clean this
method is, but it works.
