We can use the following function to check if the filesystem does support sparse files:

def support_sparse_file(directory):
    import tempfile

    with tempfile.NamedTemporaryFile(dir=directory) as tmpfile:
        # Create a file with a size of 1 byte but without content
        # (only zeros)
        with open(, "wb") as f:
        filestat = os.stat(
        return (filestat.st_blocks == 0)

We may skip the test if the filesystem doesn't support sparse file... But I think that it is already the purpose of the "largefile" resource.

If this issue is not a bug, but just that the timeout is too low, we should use a bigger timeout on this specific buildbot.
