Shared value types can not be destructed

[Benjamin Thaut]

Apperently this is by design:
http://d.puremagic.com/issues/show_bug.cgi?id=8295

To clarify: It is not possible to define a destructor that will be 
called on the destruction of a shared struct.

In a different thread Walter commeted this bug with:
"If you include an object designed to work only in a single thread 
(non-shared), make it shared, and then destruct it when other threads 
may be pointing to it ...

What should happen?"

I did try to think of a case where his scenario would actually break 
something, but couldn't find one. If someone has more knowdelge about 
this situation some clarification would be great. Maybe even a small 
code sample that illustrates the problem.

Kind Regards
