  Bug #28366: multiple load_file('a: ... ') causes entire mysqld process to hang
  
  When a Windows console application that has an open console (e.g. mysqld-nt 
  started with the --console option) encounters certain type of errors 
  (like no floppy disk in a floppy drive) the OS will pop-up an 
  "abort/retry/ignore" dialog and block the application (depending on a 
  registry setting : see http://msdn2.microsoft.com/en-us/embedded/aa731206.aspx
  for details).
  Fixed by disabling the dialog popups for every error execept a GPF and
  allignment errors. This is safe to do as the actual error gets reported
  (and handled) to mysqld.
