Here is a traceback from one failed test:
test test_lib2to3 failed
======================================================================
ERROR: test_refactor_file_write_unchanged_file
(lib2to3.tests.test_refactor.TestRefactoringTool)

Traceback (most recent call last):

OSError: [Errno 22] Invalid argument:

'/tmp/2to3-test_refactoruxve6nrz/parrot_example.py'
I also have a script which can reproduce this (attached). It happens to me
every time my offset is bigger or equal than the size of the file, no matter
whether the file is empty or offset is bigger than the size right from the
start, even when in a loop, sending in several parts. The attached example
works on my Linux machine (outputs 12 and 0), but breaks on Solaris (12 and
exception).
As I have said before, it might be just that Python (specifically sendfile
implementation) is not compiled correctly on Solaris and changes to define
guards might fix that.
