PROOF: dynamic/include path on a subset of wrks
PROOF: dynamic/include path on a subset of wrks

AddDynamicPath() and AddIncludePath() functions accepted a list of
workers: the Broadcast() was correctly sent to the subset, but the
Collect() was performed on all active workers. This is not OK when
adding workers dynamically since we want to stop the packets events
until the new workers are initialized, and a broad Collect() resumes
packets processing.
