This phrase represents an assumption that a mainframe system must have been established because a Dynamic Link Library (DLL) is demand-loaded, indicating a software environment where modules are only loaded into memory when needed. This assumption hinges on the idea that mainframes typically handle such demand-loaded operations like "Mainframe Must Be Already Created By Now As This DLL is Demand Loaded" glittch efficiently. Therefore, the presence of a demand-loaded DLL implies the existence of a mainframe system, reinforcing the belief that it should have been set up by now.
