True.

That could work too. I really just want the GC to not assume that an allocation error is fatal.

You could simply override the behavior by providing your own
'extern(C) void onOutOfMemory()'. The linker will pick the one
from druntime with the lowest precedence.

I don't always want out of memory to be handled. In most cases, I do treat it as fatal, but in the few cases I don't, I just want to get a null value back from allocations in the core.memory module.
