Of course it is.  O_APPEND always appends.  We simply do the same
locking, no seek, grab the current lof and keep going as we were.

The pointer filePtr is also used throughout for APR_XTHREAD...
just look at apr/file_io/win32/seek.c.  Simply use apr_file_seek after
locking in the Overlapped case, with APR_END, 0 as your args.
