I will do this.  Curious, what type *is* create_socket() supposed to
be fed for its first argument?  Mine seemed to get null, expect an
address, and had a string as a backup.  So I'm confused.

Just FYI, Apple's runtime environment has some builtin support for
a few magic malloc variables, including one that turns on fencing
nibble space.  I had these turned on during the quoted gdb session,
stepping by calls to fprintf, and I did also run some utilities
they have for checking leaks.  Both tools positively reported none.

Here is the output from them in case there are any "real" mac
developers who read this, I'm not very familiar with these tools
and this may help others in case I have used them incorrectly:
