The test has two things ksh93 does not happy about:

   sane way to write a pipeline.  ksh93, unlike other POSIX shells,
   does not like the two open parentheses next to each other for
   whatever reason it has.

 * It adds 256, unlike 128 that are used by other POSIX shells, to
   the signal number that caused the process to die when coming up
   with the exit status.

What is interesting is that we knew about the latter issue and had a
workaround in the test-sigchain test when verifying that SIGTERM
works OK, but we didn't have corresponding workaround for SIGPIPE.
