Sorry, I don't understand this output.  Does the "^C" mean
that you typed control-C?  If so, why did gzip continue?
It's supposed to exit if you interrupt it.  Nor do I understand
why gzip would open dtruss-test.txt more than once, or what
that __mac_syscall means.  Perhaps you can find an OS X expert
who can decipher this dtruss output.
