Nate, that's a different topic, we are talking about programs that uses 
unlink for an opened file, in UNIX and NT this file is removed when the 
program dies (as you explained to me ;-), we are talking about a possible way 
to emulate it removing the file in close and in the SIGSEGV. If the 
programmer used this trick is because s/he wants to kill the file even if the 
program crashes.
