Historically, odd spellings of this sort (in the FreeBSD kernel "exit" is 
"sys_exit") have been because exit(3) is not the same as sys_exit(2), as it 
runs at_exit handlers, etc.  Since it's the syscall handler in DTrace, 
presumably that potential ambiguity doesn't actually play out, but it's worth 
keeping a wary eye out for...
