buildbot has no builds for windows

Good news, thank you very much.
I planned to learn how to run hg tests and buildbot slave on windows. I 
do not regret that I can postpone. (It would be usable anyway, but I did 
not get far.)

Great to see that the effects of some patches are as desired. But 
file://x on linux is file:///x on windows, and test-module-imports... 
But let's discuss this in a separate thread.

I guess also it is not  a bug in hg. Maybe the problem is in the test suite.

What I do not understand is why there is only one "Abort" message on 
windows.
I tried running "hg serve -p 8888 -d" when port 8888 is in use (by a 2nd 
hg serve).
   On linux, there are two abort messages, the known one plus one from 
the child.
   On windows, I only get one error message.
So this seems to be a normal behaviour when running on this os.

Therefore it is possible that the problem is some processes hang around 
blocking some ports. It looks like hg processes: on [1], the process 
could not be started in test-treediscovery.t, but the test did some real 
communication. (Of course not what is expected. But it did exchange some 
changesets.)
I guess the processes of the last run are hanging around. As long as we 
run the same tests, they get the same port on each run. When a process 
remains, its test will fail forever. (Almost, as long as nobody kills 
the process.)
Maybe there is a problem with kill in the test suite?
