That's a separate bug.  What resources do you see busy?  Allocated
memory, I/O devices?

That's better than always calling trap, sure.  Is there any reason
you can't just do it on Macs though?  Because the problem you're trying
to work around only happens there.

Too verbose -- it prints useless information, and the actual error
message might scroll away.  No biggie of course, but why do the
workaround when not needed?
