Assuming it's unnecessary.

OSError: [Errno 22] Invalid argument
Notably, part of the fs_abilities check is calling fsync_local(), which
is trying to fsync directories even though the test to determine
whether this could be safely done failed, because
Globals.fsync_directories has not yet been updated.
I propose defaulting fsync_directories to 0 until the
get_fsabilities_readwrite() results are used to update Globals.
