wait until pipeline indicates that its output is valid in compunit test
DIV and other long pipelines only set wrmask when a result is available
the previous test, "is wrmask zero if so exit" was therefore reading
invalid data.

it was a matter of coincidence that all other compunit tests were only
one stage long that the wrmask *happened* to be valid
