TestSocketSendfile.test_it() failed with "OSError: [Errno 28] No space left on device" on PPC64LE Fedora 3.x buildbot.

It also caused troubles on "AMD64 Fedora Rawhide Clang 3.x" worker.

If I recall correctly, it writes like 8 GB of real data, not just empty files made of holes.

I suggest to either remove the test or to use way less disk space.

bpo-39488: Skip test_largefile tests if not enough disk space (GH-18261)
https://github.com/python/cpython/commit/b39fb8e847ac59b539ad7e93df91c1709815180e

Giampaolo Rodola modified the tests to skip them if there is not enough disk space. Let's see if it's enough to fix these buildbots. Since the issue was random, I close the issue and just hope that it's now fixed :-)

stage: patch review -> resolved
