A good thing that syscall `0' is a no-op.  strace(8) reports it as

Real computer scientists work from 5 pm to 9 am because that's the
only time they can get the 8 megabytes of main memory they need to
edit specs.  (Real work starts around 2 am when enough MIPS are free
for their dynamic systems.) Real computer scientists find it hard to
share 3081s when they are doing 'REAL' work.
