That is not possible unless either

 1) the process is not really dead,
 2) the X server has a bug,
 3) fvwm does not destroy the frame after the window has gone.

I've spent lots of time to get rid of any cases of #3, and what
you describe does not sound like "empty frame remains".

That's how I've tested that the frame always gets removed.

Maybe it's a problem with the X server in a virtual machine?  I
don't have such a setup to test that, but it doesn't happen on a
plain X server with or without config and neither in Xnest for me.
