Cool!  I'll take a look.  I was on PTO, so didn't get a chance yet.

Okay.  A quick look shows that it's configurable, though.  Should be
okay.  I refer to:

https://github.com/orgcandman/pw-ci/pull/12/commits/93f6baa497c85d7aca36cda6661e90f7a69d4709#diff-e2ab32f32889186bdeb0ab4f0ef55282

Okay.

The flip side is the amount of time to build.  We'd prefer to build just
one at a time.

Travis doesn't.  The ovsrobot travis build is configured to cancel a
build on a branch if a new one comes.  That way we only build the
latest.  Builds on travis take 40+ min to complete, so if a 20-patch
series came in, we wouldn't be done building it for more than half a
day.  Then if a v2+ is posted in rapid succession, we lost all this
time.  So for now, we only build the absolute last patch in the series
on Travis.

Also, the build server we run the robot on doesn't do the builds anymore
because it also got overloaded - so meson and ninja are not the actual
meson/ninja but just dummy commands.  :-/  Maybe I should re-enable and
see if things improved.
