Starting an OpenShift application seems to lock workspace

I have an openshift application starting from the IDE and can see the progress report. For some reason (not IDE related I imagine), it's taking ages.
In the meantimes, I've tried to turn a regular project into a static web project to be able to create a server adapter, but it seems like the OpenShift Start operation is locking the workspace so my change show a "waiting for background job to complete pop-up", which is persisting as the job in the background doesn't complete.
I have the impression that the openshift start job does lock the workspace and prevents many things from being doable. If it's the case, I believe it should be changed to a regular job without any lock so it's not blocking the user.
