- consider not using the __DIE__ sighandler, but instead wrap the
  potentially failing code in the eval trap blocks.

- print STDERR is buffered in test handlers, whereas warn() works
  normally. select() helps, but STDERR should be unbuffered in first
  place.

- If something goes wrong during the ./t/TEST's phase when all the
  configuration files httpd.conf, etc. are generated,
  t/conf/apache_test_config.pm now gets written, so t/TEST -clean can work
  However if the problem happens during 'make test'  for 
  some reason Makefile doesn't abort on exit from test_clean target, no 
  matter if I put exit -1, 0 or 1, and proceeds with run_tests target. 
  probably, since __DIE__ will stop the server.

  to reproduce the problem during configure() apply this patch:

- segfaults should be trapped and:
  * the test routine should be aborted, since it's possible that some
    other test will segfault too and overwrite the core file

  * it'd be cool to automatically generate the backtrace with help of
    Devel::CoreStack and save it in the file

  * once we add the backtrace feature, we don't have to abort the rest
    of the tests, but to save each bt as "backtrace.$test_path".
    => this should be very useful in smoke testing

  * later, it'd be nice to integrate this with build/bugreport.pl, so
    the bug report with the backtrace and everything we want to know
    from user's machine, including their /etc/shadow (:-) will be
    automatically posted to the list.
