bq. I think the main use case is for external beasting of various kinds.
Isn't that what ant beast is for? Which already refuses to run from outside of
the specific module, cutting down on a lot of time there.

[~mdrob]: IIRC, {{ant beast}} is not efficient at searching for reproducing
failure seeds, since parallel execution (via {{tests.dups}}) assigns the same
seed to each concurrent run. Other (aka "external") beasting methods, e.g.
[~markrmil...@gmail.com]'s beasting script (sorry, don't have a link handy),
address this weakness directly by allowing each concurrent run to select its
own seed. There are other beasting methods/scripts that achieve the same end
too (e.g. Bash loops).

> It seems to take 2 minutes and 45 seconds to run a single test with the
> latest build design and the test itself is only 4 seconds. I've noticed this
> for a long time, and it seems because ant is running through a billion
> targets first.
> I haven't checked yet, so maybe it's a Solr specific issue? I'll check with
> Lucene and move this issue if necessary.
> There is hopefully something we can do to improve this though. At least we
> should try and get some sharp minds to take first / second look. If I did not
> use an IDE so much to run tests, this would drive me nuts.
