Trying again in the hope that someone might be able to shed light.  It 
appears that END blocks are not being invoked and so I explicitly placed a 
finish_profile() in the DESTROY method of my top level handler - this also 
seems to intmittently fail to be invoked..  At a loss as to why Apache is 
not cleanly shutting down?  It appears that the cleanup phase is being 
skipped and the embedded intrepreter is not being cleanly exited. Has 
anyone witnessed this through nothing other than the injection of 
Devel::NYTProf::Apache (4.06) profiling.

Apache version: Apache/2.2.3
mod_perl: 2.0 (Apache2::RequestRec::VERSION - 2.000004)
interpretter: (64bit 5.8.8)
Devel::NYTProf: 4.06

Thoughts appreciated.
Thanks,
