Here's a concrete proposal.  Runtime is 45.7 seconds on my laptop.  It
can be further reduced, but not by more than a second or two unless you
get in the business of modifying other tests.  (I only modified
deadlock-soft-2 because it saves 5 seconds).

Admittedly the new isolation_schedule file is a bit ugly.
