Same as SMM profile feature, a special #PF is used to set page attribute to 'present' and a special #DB handler to reset it back to 'not-present', right after the instruction causing #PF got executed. Since the new #PF handler won't enter into dead-loop, the instruction which caused the #PF will get chance to re-execute with accessible pages. The exception message will still be printed out on debug console so that the developer/QA can find that there's potential heap overflow or null pointer access occurred.
