seem to suggest that returning KERN_SUCCESS should be sufficient to suppress further handling of the exception.

Any thoughts or suggestions?

Maybe have a look at https://web-beta.archive.org/web/20091230024736/http://www.brianweb.net/misc...

I was basically doing what he was doing (and my actual use case is his example -- selectively unprotect regions of memory), but my test case was an actual segfault: dereferencing a null pointer, which isn't recoverable (duh, in retrospect). When I convert my test to using actual allocated/protected memory, I get the expected results (unprotect and move on). Thanks!
