Long ago, I added an entry point called "TIFFCheckpointDirectory()"
in tif_dirwrite.c to accomplish this.
You basically call TIFFCheckpointDirectory() any time you want
the tiff file so far to be readable.
Pixar has been using it for years so you can view the incomplete output of
our renderer.
A quick check reveals that this has not been merged back into the generally
available libtiff.  We should get this merged in to the mainstream.

I'm no longer involved in libtiff support here but I'll check with the folks
who are about getting this made available.
