// Windows does have the concept of core files, called minidumps. However,
// disabling minidumps for a particular application extends past the lifetime
// of that application, which is the incorrect behavior for this API.
// Additionally, the APIs require elevated privileges to disable and re-
// enable minidumps, which makes this untenable. For more information, see

// Windows also has modal pop-up message boxes. As this method is used by
// bugpoint, preventing these pop-ups is additionally important.
