#13558 Extending leases in repo with massive requirements blocks Pants (or at least the dynamic UI) Issue created by benjyw Describe the bug The dynamic UI freezes for several seconds right before an `Extending leases`/`Done extending leases` event pair. Pants version This was seen on 2.7.1. OS MacOS. Not tested on Linux. Additional info This was seen, consistently and predictably, in a customer repo. I cannot reproduce locally. It should be noted that this customer has very large requirement sets, in both # of files and cumulative size. pantsbuild/pants
