Re: testsuite failure - 193 parallel execution

[Ralf Wildenhues]

BTW, it might be prudent to document that Autotest needs fds 6 and 7.
While AT_CHECK commands are run in a subshell, other commands in the
testsuite aren't, and the fact that the job fds are open in the test
group code can easily break both the job handling and the test group
code.  Or we bite the bullet and use another subshell to actually be
able to close the fds for the test group code.  :-/

Cheers,
