I've taken Dean's suggestion to use a flag and work directly with the buffer. Seeing expected behavior when setting the flag in a test program.

I've also made the change to read directly from the buffer instead of creating new aligned storage.

Considering non-instrumented functions, I think I should remove the code that rewrites childless tail exits into normal exits. I'll post that in another revision.
