   It is an incorrect design to call C++ destructors from the OS in kernel mode (PROTECTED and KERNEL builds) or with interrupts disabled.  Calling the destructors introduces new problems similar to those discussed in Issue #1263 and which I am working toward fixing in PR #1328 
   
   Executing the destructors in kernel mode is a security violation.  Running the destructors with interrupts disabled is just wrong.  What if they need to wait for an event in a busy loop?  No user code should ever run with interrupts disabled:
   
   This change should not be done.  You should consider contributing to the correct fix that does not introduce additional problems of this nature.  I would recommend that this change not be merged is it is not correct.  It is expedient... but it is wrong.  That is forbidden in the INVIOLABLES.txt:
   
       The Enemies
       ===========
       
       No Short Cuts
       -------------
       
         o Doing things the easy way instead of the correct way.
         o Reducing effort at the expense of Quality, Portability, or
           Consistency.
         o Focus on the values of the organization, not the values of the Open
           Source project.  Need to support both.
         o It takes work to support the Inviolables.  There are no shortcuts.
   
   Let's do things right.
