Yes, they are.  Quoth man perlmod:

       An "END" code block is executed as late as possible, that is,
       after perl has finished running the program and just before
       the interpreter is being exited, even if it is exiting as a
       result of a die() function.  (But not if it's morphing into
       another program via "exec", or being blown out of the water
       by a signal--you have to trap that yourself (if you can).)

One option is to install a signal handler somewhere to clean this up.
Perhaps we can just set $SIG{INT} to a function that calls "die" or
something like that.  But this doesn't solve the problem if the system
crashes while a test is running, for instance, so perhaps your idea of
moving these directories to inside tmp_check/ is good.
