What I've done in similar situations is to create a batch-file called
cmd /c %*
exit /b %ERRORLEVEL%
Then write my own ShellCommand() wrapper that just runs
'cmd /c call wrap.cmd' + args.
(The 'cmd /c call' ensures correct error level propagation from batch

Not so that all subsequently started processes get the same env, AFAIK.

That might work, but I haven't tried it. You can't specify a batch file
as a service (nor a regular exe, it needs to export some
service-specific functions for start/stop/pause), so you'd have to go
through a wrapper executable, such as srvany.exe (available in the
Windows resource kit).
Using that, to start cmd.exe, to run your wrapper then run buildbot.py

The ShellCommand is the simplest way.
