cleanup routines can be executed at any point during the execution of the
body, including even before the body has done any real work. In those
cases, cleanup routines should be careful to not raise spurious errors so
as to not "override" the actual result of the test case.
This is just general good coding style but is not a problem in practice
for these specific tests. (The way I discovered the issue, though, was
due to a regression I introduced in Kyua itself while refactoring some
internals.)

traced by another process such as a debugger). The parent process does
need to check for matching orphan pids to avoid returning ECHILD if an
orphan has exited, but it should not return the exited status for the
child until after the debugger has detached from the orphan process
either explicitly or implicitly via wait().
Add two tests for for this case: one where the debugger is the direct
child (thus the parent has a non-empty children list) and one where
the debugger is not a direct child (so the only "child" of the parent
is the orphan).

resulting in the process' status being returned twice to its parent.

As jhb noted, the actual mmap(2) implementation is under sys/vm, not
sys/kern/, so the correct logical place is tests/sys/vm/, not
