To kill child processes on Windows, one must walk the tree and kill
those as well. wxWidgets has an implementation in src/msw/utils.cpp:
http://cvs.wxwidgets.org/viewcvs.cgi/wxWidgets/src/msw/utils.cpp
See the differences between wxKill and wxKillAllChildren . I would also
mention that wxWidgets implements SIGKILL as TerminateProcess(), and
SIGTERM as sending a QUIT message to the process.
