   How is parity handled in larger systems?  I know about ECC; are there
   any larger systems that use just parity, but attempt to handle it more
   reasonably?  How do larger systems handle ECC correction failures?

Well, on Sun 3/50s, it panics and reboots.  Hardly a _large_ system,
but get much larger and they tend to have ECC.

Suns with ECC print a diag when correcting; I have never seen an
uncorrectable error.
