Strange, I couldn't reproduce this when I first tried, but now I can 
reproduce it every time on Emacs 21.3, 22.3 and CVS trunk.

Perhaps it was a recent OS patch that caused this behaviour. It does not 
even seem to be linked to the fact that the shell window is hidden, as 
changing w32-start-process-show-window does not improve the problem.
