other trivia: when I transfer to San Jose, I got to wander around
datacenters in silicon valley, including disk engineering & product test
(bldg14&15) across the street. They were doing prescheduled, 7x24,
stand-alone mainframe testing. They mentioned they had recently tried
MVS, but it had 15min mean-time-between-failure, requiring manual
re-ipl/reboot in that environment. I offered to rewrite I/O supervisor
to make it bullet-proof and never fail enabling any amount of on-demand,
concurrent testing (greatly improving productivity). Downside was they
would point their finger at me whenever they had problem and I was
spending increasing amount of time diagnosing their hardware problems.
