Yao, yes, sorry system call number, vis:

  updateSyscallEnter (Task task, int syscallNumber)

That way all observers of system calls would be, as part of the entry, 
be directly notified of which system call is involved; and during exit 
that information would clearly not be involved.  The client can then 
decided if it wants to retain the value.
