                      3:
                      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.
