+ @c wxSIGTERM under Windows. Moreover, under Windows, @c wxSIGTERM is
+ implemented by posting a message to the application window, so it only
+ works if the application does have windows. If it doesn't, as is notably
+ always the case for the console applications, you need to use @c wxSIGKILL
+ to actually kill the process. Of course, this doesn't allow the process to
+ shut down gracefully and so should be avoided if possible.
