How do you tell Windows to do that?

Via the SetErrorMode call.

Since the Windows buildbot already uses the win32 extensions, I just used the existing win32api wrapper (although through ctypes is very easy too). In my case I just surrounded the reactor.spawnProcess call in buildbot/slave/commands.py with:

old_err_mode = win32api.SetErrorMode(7) and win32api.SetErrorMode(old_err_mode)

I suppose I should really tweak that to 0x8007 rather than just 7 to include missing file dialogs (like when a removeable device is not available).

Since the error mode is inherited by child processes (unless explicitly overridden in the CreateProcess call), this effectively covers the primary child process and any others it may spawn during execution, so it works even though buildbot uses an intermediate command interpreter to execute whatever command is requested.

We had a bit of discussion about this recently on the py3k devel list, in regards to failures in the python buildbot tests, in regards to more local changes within Python itself.
