cleanup handlers are just callbacks run when a memory pool goes out of 
scope.  your test suggests that the memory pool allocated for the 
request is going out of scope before the response handler runs, which is 
odd indeed :)

I'd try these things:

  o use a PerlLogHandler instead of a PerlCleanupHandler

  o push your cleanup from an earlier phase instead of httpd.conf

  o call $r->cleanup_register from an earlier phase instead of pushing 
a  handler
