I believe this is not possible with libtiff, unfortunately.

I have the same problem. My library does interleaved writes to a set
of separate TIFF files as data comes in, then in a second pass gathers
up the separate TIFFs into a single, large image. It's ugly, slow, and
needs a lot of disc space :-( but unavoidable, I think.
