You are calling the dictionary globvars as a function then the error.
The fixed line is:
execfile('/scripts/second.py', globvars, locvars)
What you want is the function globals().
Try putting this line in second.py:
print globals()['infile']
Using the dictionary returned by globals() you can make second.py to
read the contents of testexec.py's globvars dictionary.
locvars is populated with the local variables of second.py and that is
what you want.
Regards.

See "-d" zip's parameter in man zip.

If you print __name__ in second.py its value is '__builtin__', because
of that your "main" doesn't execute.
Try adding this to test_exec.py before the execfile() call:
globvars[ '__name__' ] = '__main__'
It looks like a ad hoc fix but i couldn't find any doc about the change
of __name__ to 'builtin' of a python script being run
from another with execfile().
