Remember, the VCL source code manages its memory manually, but the .NET FCL does not. Without GC, on a 2 GB machine, I can exhaust all available memory and crash the system just by moving the mouse around for a few seconds while the application is running. I imagine that this is an issue that will be fixed before the product ships, but perhaps the feature is intended only for 64-bit machines with more memory. I'm sure there are other issues I haven't found yet. I wouldn't want to be responsible for harming someone's machine. Torbins, I’m not comfortable with doing that just yet.

A little experimentation shows that you can patch up the headers with a hex editor easy enough. However, the resulting EXE is weird. It seems to disable garbage collection in .NET. I guess this is for compatibility with the VCL, but I haven't figured out how they do that yet. Thanks for this.
