Yes, it works fine due to the topological sort of the DSP graph into a
DSP chain - but DSP is block-based, so be aware that each block is read
as a whole before it is written - this probably only matters if you
wanted to write to a different location for non-block-sized feedback
effects.  Also you might have little glitchy issues when table length
isn't an exact multiple of the block size.

There are some examples of [tabreceive~]--stuff--[tabsend~] in the docs,
probably in the FFT section of the manual.

A simple looper might be a [tabplay~]--stuff--[tabwrite~] thing with the
tabplay~ and tabwrite~ both triggered from the same source, and
retriggerd by the tabplay~ "done" bang...
