My guess is that you import some file that defines the buildslaves.

buildbot's reconfig is implemented by rerunning the code in the
master.cfg file. The nature of python is such that an import only
loads the indicated file the first time it is run (so if you change the
file, python won't see it). This can be somewhat worked around by
calling reload, although the behavior of that can be tricky.
