Hmm, there are something on the order of 10000 SQL commands in our
regression tests, so even assuming perfect randomness you've exercised
SIGTERM on maybe 10% of them --- and of course there's multiple places
in a complex DDL command where SIGTERM might conceivably be a problem.

Who was volunteering to run this 24x7 for awhile?

Uh, where's the randomness coming from?
