1. Never reap ithreads via modperl's Interpreter tune.  Once modperl spins
up a new ithread for capacity response, leave it alone until you logrotate
httpd with a graceful restart.

2. Consistently Disable the use of per-request ENV vars populated by
modperl.

3. Enjoy some high-performance efficiency boosts in your modperl handlers
with sealed.pm, (but avoid reentrancy/recursion for those subs, or you may
segfault).
