Why kernel debug engine doesn't break on kernel-mode traps?

Hello!

In kernel debugging mode (for example, with WinDbg), there is no way
to get a first-chance break on some exceptions (divide by zero,
integer overflow, page fault in non-paged area etc.). Why NT debug
engine does not break into debugger processing these exceptions but
generates a bugcheck first?

Regards,
Eugene
