Please review a test improvement to avoid counting unexpected handles.
The test for 8239893failed when non-test activities used handles.
The test is modified to do a warmup phase spawning some processes and
It then runs the test to create processes looking for no significant
increase in handles.
The execution mode is limited to the interpreter to avoid potential side
effects of compilation.
The error condition was corrected to look only for increases in the
number of handles.
Previously, it looked for a 10% delta between the minimum and maximum
count of handles.
