Runtime.unloadLibrary does not return

[cal]

Following the D win32 dll example (http://dlang.org/dll.html), I 
created a d dll with a simple exported function, which i then 
dynamically load and call (just like the example). This works 
fine, however Runtime.unloadLibrary does not return. I do however 
get the "DLL_PROCESS_DETACH" message, so it gets at least that 
far.

In fact, if I have code after the Runtime.unloadLibrary call, the 
program crashes (without code following the call, it just hangs).

Has anyone else seen this problem? I get this with both dmd 2.060 
and 2.061.
