[yt-users] parallel config issue

[Matthew Turk]

Hi Sam,

This is fixed in hash 19e3e5f1c0b9.  The issue was simply that the
config system does some shortcuts, and for some reason this did not
show up in the regression tests I've been running.

Related to that, the regression tests should become publicly
accessible relatively soon -- one of the conditions of the 2.0 release
is for a public regression test server, which we're almost done with.
