If you ignore a problem long enough, it'll be fixed by someone else.

FreeBSD 5.2-RC with either libthr or libkse enabled (instead of the default
libc_r) is confirmed to be operational with the worker MPM.  Add notes to
STATUS and README.platforms (as there is now an upgrade path that may be
reasonable for those needing threads).

[No soak tests run, but it serves pages - which is an improvement over before]

-      Aaron says: I spent some time disecting this and have come to
-              the conclusion that it is not a problem in the worker MPM
-              (or at least, it is not isolated to a problem in worker).
-              I'll list some of the problems I'm seeing in case someone
-              else wants to pick up where I've left off:
-               - Delivery of just about any signal to one of the child
-                 processes will send it into an infinite loop as well.
-               - Even though the parent is spinning out of control,
-                 at first the child or children will appear to work
-                 properly. At times it is possible to get it into a state,
-                 however, where a request will hang until another concurrent
-                 request "kicks" the first, at which point the second will
-                 hang. My theory is that this has to do with the
-                 pthread_cond_*() implementation in FreeBSD, but it's still
-                 possible that it is in APR.

-      Justin adds: Oh, FreeBSD threads are implemented entirely with 
-                   select()/poll()/longjmp().  Welcome to the nightmare.
-                   So, that means a ktrace output also has the thread 
-                   scheduling internals in it (since it is all the same to 
-                   the kernel).  Which makes it hard to distinguish between 
-                   our select() calls and their select() calls.  
-                   *bangs head on wall repeatedly*  But, some of the libc_r 
-                   files have a DBG_MSG #define.  This is moderately helpful
-                   when used with -DNO_DETACH.  The kernel scheduler isn't 
-                   waking up the threads on a select().  Yum.  And, I bet 
-                   those decrementing select calls have to do with the 
-                   scheduler.  Time to brush up on our OS fundamentals.
