Some Notes on using VCSServer with gunicorn and gevent:
I tested to activate gevent also in the VCSServer but it seems not ready to be used with gevent. Most tests are running fine (test in CE and ac-tests) but some of them are failing because of a worker timeout in the VCSServer. I assume that the VCSServer uses some libraries which are not compatible with gevent. Maybe it is the same problem that we encountered with pycurl. Something may use C API (or similar) functions to implement thread synchronization.
