Write to TAP stream during execution

[davidmatson]

From a quick look at the code, it appears that tap.h currently holds all results until the test run completes, and then writes to output then. Is that understanding correct?

If so, I believe that conflicts with how TAP is designed to work, as a stream, with results written while tests are running:

Can the implementation be changed to stream output, rather than buffering it and writing at the end?
