C# Interop

>> I assume that you do quite a lot of initialization for TLS

I'm not directly, but Juno has a number of static class constructors that allocate
static members, and Outlook creates lots of threads (for example, i see the static
constructor of the module juno.com.core get called 20+ times on startup).
The Juno lib predates the TLS changes in D2 so i guess that some of these static
variables don't need to be thread local, but i haven't had chance to investigate that.


>>Are you using callbacks into the C++ DLL from the module ctors

The D dll just exports a couple of 'C' functions that the C++ dll calls. There are
no calls in the other direction.


>> that might work better if the C++ part also uses thread local storage

The C++ dll uses ATL for it's COM stuff, and i'm not sure what that does with TLS
in the background.

I'll try your suggested change tommorow.

Thanks,
