Windows will not actually delete a file as long as there is any
open handler for it. Until we close the last open handler, the
file is kept alive as "pending delete".
Obviously this has been breaking the log rotation mechanism for
some users. Work arount that by checking the "DeletePending" flag
manually in tail_fs_check().
