Choice. I was able to avoid the allocation in this specific case:

http://boost.cvs.sourceforge.net/boost/boost/libs/thread/src/tss_hooks.cpp?revision=1.4&view=markup

but in general, objects that need to have program lifetime cannot be deleted 
safely. Many industrial-grade leak checkers will not report such objects as 
leaks, because they aren't.
