Why can't the file with the binding be added to the request processor reload list in the same way the APM adds a file that you've requested be reloaded?
That gets it into every thread's interpreter ...
Not quite every thread - since apm_load_any_changed_libraries is only called in the request processor, APM watches only work in connection threads (and not in scheduled procs, for example).
Hmmm... Although I guess ad_schedule_proc could be altered to prepend a apm_load_any_changed_libraries to any procs scheduled...
