  That sounds good, it should solve half my problem (determining what
system calls my programs are making).  But it won't allow me to determine
what system calls other peoples programs are making.  In UNIX I often use
strace to determine what programs do so I can tell what is going wrong when
they just give strange error messages and exit...
