New submission from Sebastian Wiedenroth <wi...@frubar.net>:
I'm investigating some test failures related to sendfile on illumos:
testCount (test.test_socket.SendfileUsingSendfileTest) ... FAIL
testCountSmall (test.test_socket.SendfileUsingSendfileTest) ... ok
testCountWithOffset (test.test_socket.SendfileUsingSendfileTest) ... ok

testNonBlocking (test.test_socket.SendfileUsingSendfileTest) ... ok
testNonRegularFile (test.test_socket.SendfileUsingSendfileTest) ... ok
testOffset (test.test_socket.SendfileUsingSendfileTest) ... ERROR
testRegularFile (test.test_socket.SendfileUsingSendfileTest) ... ok
testWithTimeout (test.test_socket.SendfileUsingSendfileTest) ... FAIL
testWithTimeoutTriggeredSend (test.test_socket.SendfileUsingSendfileTest) ... ok

During handling of the above exception, another exception occurred:

Ran 11 tests in 33.603s
FAILED (failures=2, errors=1)
Looking at the testCount case I could observe repeated calls to sendfile() with
out_fd=7, in_fd=6 off=0, len=5000007 which returned -1 with errno set to EAGAIN.
