Yeah, it could be. Could this result in fork error messages as we are
seeing all over the place?

Nice trick to use pinfo as a work-around, but i could fear that others
also call kill() at this critical time. Is there an actual fix for
kill() in the cooking? I could fear that tools like "make" actually
call this all over the place, especially if its aborting running
processes. And why did this work before?

That looks OK. Ignore the actual result of the makefile, 
its just garbage :-). Its only to reproduce this error.

Thanks again for helping,
