        !             4: Some Alpha AXP OSF/1 binaries directly use the facilities provided by
        !             5: the Mach kernel that is the basis for OSF/1.  These include (but are
        !             6: surely not limited to) 'dd', 'ps', and 'w'.
        !             7:
        !             8: Invariably, the symptom that these binaries display is that they crash
        !             9: with an "unimplemented system call" trap (SIGSYS signal) for a syscall
        !            10: that has a negative number.  In general, binaries that use the Mach
        !            11: syscalls appear to invoke task_self() as their first syscall.
        !            12:
        !            13: The name, number, and number of arguments for each Mach syscall is
        !            14: given below; this information was gleaned by looking through the OSF/1
        !            15: libmach.a's object files with dbx, then double-checked against the
        !            16: contents of OSF/1's <mach/syscall_sw.h>.
        !            17:
        !            18: These calls would be very difficult to implement properly in the
        !            19: OSF/1 emulation code; by its very nature, NetBSD is not Mach, and we
        !            20: don't and can't provide the underlying facilities that it does.
