Hi Steve, my buffers are allocated in shared memory by a server process that 
then sends data to Nuke. If I don't tell the server that my Op is no longer 
using the shared memory, then the server process will still hold a reference to 
the shm and it will never be freed (at least I think so...). What I think I 
need therefore is to have a hook that's guaranteed to be called when Nuke 
closes so I can release the resource.

Also note, Anders, that nothing is left hanging. Even though your destructors 
are not called, all heap-allocated space associated with a process is 
automatically freed when the process terminates. So, when you exit Nuke, you 
get your memory back.

I'm finding that Nuke will sometimes destroy my Op, and sometimes not. If I 
create half a dozen plugin nodes then delete them, maybe 2 will call 
MyOp::~MyOp(). Then when I quit Nuke, those destructors still won't be called.

In my particular plugin I allocate ~25MB of interprocess shared memory per Op, 
so leaving this hanging around is a bit of a deal. Is this something to do with 
the undo functionality or something else that I can turn off? Is there some 
other hook I can use that *is* guaranteed to be called when an Op is no longer 
needed?

Cheers,

Anders
