Regarding

PANTS_CONCURRENT

. What does the following from the documentation mean? "Enabling this option requires parallel Pants invocations to block on the first". I'm trying to use Pants in conjunction with Tilt in order to have Pants build the images, and have Tilt bring them up using docker-compose. However, I'm getting really terrible performance (slow builds) when using

PANTS_CONCURRENT

and 8 concurrent pants-instances, but also very slow builds without it set, given that each of my 20+ services have to wait for the previous to finish. Am I missing something obvious that would speed this up significantly?
