[erlang-bugs] case_clause in io:put_chars during common test run

Hi Siri,
Thank you for looking into this but, I just found the code responsible for the
error - on our side:
At the end of each test suite (via a common test hook) we kill all processes
that have not been running before the suite was started (to make sure that
previous test suites don't influence new ones). This includes processes
spawned without linking to the originating process - the rest is already
killed by common test.
There are some exceptions and apparently something changed and we killed too
many processes. In this case it was the following:
initial_call: {erlang,apply,2},
current_function: {prim_file,drv_get_response,1}
There is no safe way to filter that process out (based on current_function or
any other process_info I'm aware of) and I'd rather use some common test
functionality isolating test suites but so far I'm not aware of any...
-> this would be a useful extension to common test though
