Agreed, but some recoverable errors are not currently checking the
exception table.  For example, sys_query_module = 0xe000000000a64000,
id 0xc000000000a64000 (same address, but region 6) fails with 'General
Exception: IA-64 Reserved Register/Field fault (data access)'.  The
more resilient I can make kdb, the better I like it, hence my wish to
add recovery to ia64_fault().
