"""Check to see if the working set produces a good executable.

This test script is made for the noincremental-prune test. This makes sure
that, after pruning starts (>1 bad item is found), that the number of args sent
to the switch scripts is equals to the actual number of items (i.e. checking
that noincremental always holds).
