Hi.

We run a number of slaves on Win32 (and the master on OpenBSD). Works 
pretty well.

I didn't have to do that. But there was some other issue in twisted that 
was related. Have you tried searching the twisted tickets for something 
similar?

What we did was to specify the svn-path in the buildstep (c:\program 
files\subversion\bin\svn.exe) .. but I haven't digged into _why_ we had 
to do that. (Because it is, as you say, on the PATH.)

That's strange. Those parts have always worked well for me.

I applied a patch to twisted that helps with the forced termination of 
process. See these tickets:

Buildbot ticket: http://buildbot.net/trac/ticket/77
Twisted ticket: http://twistedmatrix.com/trac/ticket/2726

Some. Not enough though.
