Hi! Ok, I haven't been able to build and test perl multi-threaded
successfully since 5.8.2. I need a multi-threaded perl interpreter
since I'm running Apache 2.0.49 (soon to upgrade to 2.0.50) with the
"worker" MPM, which is a multi-threaded MPM.

The wait.t test is the test that is failing:

Failed Test Stat Wstat Total Fail Failed List of
Failed
-------------------------------------------------------------------------------
../ext/threads/shared/t/wait.t 102 30 29.41% 27-41
76-90
24 tests and 488 subtests skipped.
Failed 1/881 test scripts, 99.89% okay. 30/86226 subtests failed,
99.97% okay.

When I run the wait.t test individually, I get these results:

[tom@linux t]$ ./perl -I../lib ../ext/threads/shared/t/wait.t

Any idea on how I can find out why the above range of tests are
failing?

Thanks in advance!

Peace...

Tom
