Re: parallel autotest [2/3]: Implement 'testsuite --jobs'.

[Ralf Wildenhues]

Hello Eric,

Ping ping.

It would be nice to know if it's just lack of time holding this up
(in which case, forget about this ping, and please take your time),
or issues with the patch (which could maybe be addressed in the
meantime).  It may be useful to note that the patch adds a couple
of risky tests (because they require timing to succeed).

Thanks,
Ralf
