I use something like this to conditionally reload:

    import sys, os, stat
    sys.path.append(os.path.expanduser('~buildbot/master'))
    import buildbot_nut

    py_time  = os.stat("buildbot_nut.py").st_mtime
    pyc_time = os.stat("buildbot_nut.pyc").st_mtime
    if py_time >= pyc_time:
        reload(buildbot_nut)

It sounds like you would need to do this several times over, once per
independent builder.

Also, I have had better luck when I avoid using the 'from foo import
*' syntax. You may want to just say 'import buildsteps' and use
"buildsteps.step1" instead of just "step1".
