-{{{module_index}}} lets us know which module registered us.  {{{callback}}} is the Sub PMC that should be invoked, and {{{hll_data}}} is a PMC that should be passed to the callback.  {{{modparrot_meta_request_cleanup}}} is a generic callback function that uses this data to set the module index and call the subroutine.
+We use the actual Apache {{{module}}} struct instead of the usual {{{module_index}}} idiom here, as cleanups are not real Apache hooks and therefore don't have a module array to index in the configuration.  More importantly, the timing of cleanup registration and execution is indeterminate, since cleanups can be registered during the request, and pools can be destroyed at various points during a connection.
