We have git polling enabled for a multijob project which requires the use of a local workspace as are using the "polling ignores commits with certain messages" option. Each build for this project takes around 1 hour.
If a build is running when polling triggers (either via schedule or from using the notifyCommit endpoint) it has to wait for the build that is running to finish before completing. This significantly reduces the throughput of our builds.
When looking at the Jenkins threads we see polling waiting on acquiring a workspace lock

At this point if we view the Git Polling Log for the project all we see is

Is there a way to have polling proceed whilst another build is in progress?
