Memory leak - only with large data set

[Roger]

Thanks you for your feedback. Yes, we are using win32 on windows. 
Sounds nice with a 64 bit compiler! Do you know when it will be 
available?

We tried to manually manage the memory by using: 
GC.free(items.ptr);
Where "items" is the large array. It worked when pinvoked from a 
(nonthreaded) windows application. The memory was released. 
However in a threaded web application environment it failed.
