Comment 33 for bug 313202

about the compilation pause - i did not experience it so that's weird, i'll see if i can replicate that.
about multiple calls - it should inject arguments to a copy but i probably forgot to change it in the one of the steps, i'll see what's up
about your own test - my first impression is that it's an edge case i didn't notice. i think i know what it is and it shouldn't take too long to fix

stay tuned i guess
