So I'm worried that the system might have a version
of strace that doesn't support say newfstatat for example.
Now my removing of the -e ... above will avoid the immediate:
  strace: invalid system call `newfstatat'
But strace may then output something that `grep stat..` doesn't match,
thuse messing up the counts and failing the test.

I'll sleep on it as I'm rushing off now.

thanks,
Pádraig
