Right now it is, and many upload single tiles only. It's a significan part of the upload handler to decide whether it's a complete tileset.
Some need to e.g. split their tilesets in across serveral upload files as their ISP's proxy only allows small files to be uploaded, apparently.

It's unzipped to the disk partition where the tiles are. So the final mv to their end destination is cheap. Unzipping into RAM disk and then moving them to the partition were equally expensive. We had tried a RAM disk before on the dev server.
