Or simply ref-count the memory.

However (I have seen the crash myself), I can not reproduce the problem
once no kind of printf is involved. I would suggest to not use a broadcast
xcall here, but do it for each cpu in turn, which will make the output
readable.

Alternatively: collect a list of results and print them all after all cores
are done.
