You can't. GetNextEvent is called when the application wants another
event.  If the app's hard at work, it's not going to call it, being
busy already.  Thus your GNEFilter won't get called either. Your
response rate is determined by the application; not by you.

Instead of using the GNE filter, try applying a headpatch to PostEvent or
PPostEvent.  These calls are made by the operating system at the moment
the event occurs; not at the moment the application choses to hear
about it.
