Raspberry Pi write cycles

I did have a case where the Pi I was using as secondary DNS/DHCP and as the
secondary backup server (using USB spinning disk) destroyed its SD card.

But then it turned out not to be the load at all.  No matter what I ran on
that Pi, it would corrupt its SD cards in a matter of weeks (the symptom
was that the fourth bit of some bytes would just stick on).  I assume it
was just something broken in the Pi itself.

I will state here, for the record, that if someone can spam effectively --
or be a botnet C&C node -- from TOPS/10 on a PDP-10 emulated on my Pi, my
irritation at having my systems abused will probably be overwhelmed by my
admiration at their dedication.

(Traffic encryption via simh is incredibly painful.  You have to turn login
delay waaaaay up to run NetBSD on VAX on a Pi if you want to be able to ssh
into it; the machine itself runs fine-ish, but the zillions of cycles to
encrypt the traffic swamps it in no time.)

And, you know, if you manage to cause my SD cards in those machines to
fail, well, gosh, guess I'm out $10 or so for a new one.  I'm not bothering
to back up any of the stuff inside 'em, btw (so those of you using 'em,
seriously, save your work elsewhere if it's precious--and, um, yeah, unless
you're on OpenVMS, TOPS-20, or ITS, you don't have a TCP/IP stack and since
you don't have a direct terminal interface into it, that probably means
copying and pasting from the terminal session...but if you have something
you really want off it that's larger than a couple of screens full, just
write me a note and I can likely extract it for you more reasonably).
