On the Windows side I modified
/usr/lib/python2.6/site-packages/buildbot/slave/commands.py
  Added to SlaveShellCommand.start()
  printing to a file:

f=open('foodles.txt','w')
f.write( "In buildbot.slave.commands.py SlaveShellCommand.start()\n" )
f.write( "%s" % args )
f.close()

And I tried to build.
The file is created in /home/build/Buildbot_slave/foodles.txt
The file contains:
In buildbot.slave.commands.py SlaveShellCommand.start()
{'workdir': 'build', 'env': None, 'want_stderr': 1, 'logfiles': {},
'command': ['touch', 'foodles.txt'], 'timeout': 1200, 'want_stdout': 1}

I guess I'll continue down this route.
